Hello I have got a question about TableView in JavaFX and populating the table with data from an object in the model via a getter method of this object, which is part of the model .
First of all, here is my model:
package model;
import java.util.List;
public class Carmodel {
private int carmodelID;
private Cartype cartype;
private Manufacturer manufacturer;
private DrivingLicense drivingLicense;
private String label;
private int seats;
private int kw;
private String fuelType;
private double priceDay;
private double priceKM;
private int axes;
private int loadVolume;
private int loadCapacity;
private List<Equipment> equipmentList;
public Carmodel() {
}
public int getCarmodelID() {
return carmodelID;
}
public void setCarmodelID(int carmodelID) {
this.carmodelID = carmodelID;
}
public Cartype getCartype() {
return cartype;
}
public void setCartype(Cartype cartype) {
this.cartype = cartype;
}
public Manufacturer getManufacturer() {
return manufacturer;
}
public void setManufacturer(Manufacturer manufacturer) {
this.manufacturer = manufacturer;
}
public DrivingLicense getDrivingLicense() {
return drivingLicense;
}
public void setDrivingLicense(DrivingLicense drivingLicense) {
this.drivingLicense = drivingLicense;
}
public String getLabel() {
return label;
}
public void setLabel(String label) {
this.label = label;
}
public int getSeats() {
return seats;
}
public void setSeats(int seats) {
this.seats = seats;
}
public int getKw() {
return kw;
}
public void setKw(int kw) {
this.kw = kw;
}
public String getFuelType() {
return fuelType;
}
public void setFuelType(String fuelType) {
this.fuelType = fuelType;
}
public double getPriceDay() {
return priceDay;
}
public void setPriceDay(double priceDay) {
this.priceDay = priceDay;
}
public double getPriceKM() {
return priceKM;
}
public void setPriceKM(double priceKM) {
this.priceKM = priceKM;
}
public int getAxes() {
return axes;
}
public void setAxes(int axes) {
this.axes = axes;
}
public int getLoadVolume() {
return loadVolume;
}
public void setLoadVolume(int loadVolume) {
this.loadVolume = loadVolume;
}
public int getLoadCapacity() {
return loadCapacity;
}
public void setLoadCapacity(int loadCapacity) {
this.loadCapacity = loadCapacity;
}
public List<Equipment> getEquipmentList() {
return equipmentList;
}
public void setEquipmentList(List<Equipment> equipmentList) {
this.equipmentList = equipmentList;
}
As you can see there is a specific member (private Manufacturer manufacturer) It is an object from the type "Manufacturer". And the Manufacturer class looks like this:
public class Manufacturer {
private int manufacturerID;
private String name;
public Manufacturer() {
}
public int getManufacturerID() {
return manufacturerID;
}
public void setManufacturerID(int manufacturerID) {
this.manufacturerID = manufacturerID;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
This is my controller for the JavaFX View:
public class CarmodelController implements Initializable {
CarmodelRepository carmodelRepository;
#FXML public TableView CarmodelTable;
#FXML public TableColumn<Carmodel,Integer> tableColumnID ;
#FXML public TableColumn<Carmodel,String> tableColumnLabel ;
#FXML public TableColumn<Carmodel, String> tableColumnManufacturer ;
#FXML public TableColumn<Carmodel,String> tableColumnCartype ;
public void initialize(URL location, ResourceBundle resources) {
carmodelRepository= new CarmodelRepository();
List<Carmodel> carmodelList= carmodelRepository.readAll();
ObservableList<Carmodel> carmodelObservableList = FXCollections.observableArrayList(carmodelList);
tableColumnID.setCellValueFactory(new PropertyValueFactory<Carmodel, Integer>("carmodelID"));
tableColumnLabel.setCellValueFactory(new PropertyValueFactory<Carmodel, String>("label"));
tableColumnManufacturer.setCellValueFactory(new PropertyValueFactory<Carmodel, String>("manufacturer")
And here is the problem:
Can I do here something like PropertyValueFactory("manufacturer.getName()"); This way it didn't work. It just populate the column of the table with memory adress
So my question is:
How can I get the name of the manufacturer, normally, in other code, you can do this by calling the method: "manufacturer.getName();" and it will give you the String with the name of the manufacturer, but how can I do this while I will populate the table with these specific carmodels?
And the end of the controller code ( filling the Table with values).
CarmodelTable.setItems(carmodelObservableList);
}
Thank you in advance!
You can do
tableColumnManufacturer.setCellValueFactory(cellData ->
new ReadOnlyStringWrapper(cellData.getValue().getManufacturer().getName());
The setCellValueFactory method expects a Callback<CellDataFeatures<Carmodel, String>, ObservableValue<String>> object. Hence cellData in this code is a CellDataFeatures<Carmodel, String> object, and cellData.getValue() gives the CarModel object for the row. Then cellData.getValue().getManufacturer().getName() gives the value you want; you just have to wrap it in a ReadOnlyObservableWrapper to get an ObservableValue<String> containing that value.

In my project, we have to create a system where we create an object Facility and we have to run inspections and maintenance on it to check if it's working. We created a Facility object and then we created a state machine that changes the state of the Facility to resting, working, maintenance, or working.
Here is the SuperFacility class:
import java.util.Map;
public interface SuperFacility {
public void setName(String name);
public void setAddress(String address);
public void setDescription(String description);
public void setRefNumber(int refNumber);
public void setCapacity(int capacity);
public void setCost(double cost);
public void setProblemRate(int problemRate);
public String getName();
public String getAddress();
public String getDescription();
public int getRefNumber();
public int getCapacity();
public double getCost();
public int getProblemRate();
public void oxygenator(boolean oxygenator);
public void nuclearReactor(boolean nuclearReactor);
public void innerAirlocks(boolean innerAirlocks);
public void externalAirlocks(boolean externalAirlocks);
public void comms(boolean comms);
public void waterMaking(boolean waterMaking);
public void startMachines();
public Map getMap();
public void getFacilityStatus();
public void getFacilityStatus(Map<String, Boolean> map);
}
Here is the Facility class:
import java.util.*;
public class Facility extends StateMachine implements SuperFacility {
public String name, address, description;
public int refNumber, capacity, problemRate;
private double cost;
private Map<String, Boolean> map = new HashMap<String, Boolean>();
private boolean[] machines = new boolean[6];
private boolean oxygenator, innerAirlocks, externalAirlocks,
comms, nuclearReactor, waterMaking;
private final int numberOfMachines = 6; // Number of Machines inside Facility
// Setters
public void setName(String name){
this.name = name;
}
public void setAddress(String address){
this.address = address;
}
public void setDescription(String description){
this.description = description;
}
public void setRefNumber(int refNumber){
this.refNumber = refNumber;
}
public void setCapacity(int capacity){
this.capacity = capacity;
}
public void setCost(double cost){
this.cost = cost;
}
public void setProblemRate(int problemRate){
this.problemRate = problemRate;
}
// Getters
public String getName(){
return name;
}
public String getAddress(){
return address;
}
public String getDescription(){
return description;
}
public int getRefNumber(){
return refNumber;
}
public int getCapacity(){
return capacity;
}
public double getCost(){
return cost;
}
public int getProblemRate(){
return problemRate;
}
public void oxygenator(boolean oxygenator){
this.oxygenator = oxygenator;
}
public void nuclearReactor(boolean nuclearReactor){
this.nuclearReactor = nuclearReactor;
}
public void innerAirlocks(boolean innerAirlocks){
this.innerAirlocks = innerAirlocks;
}
public void externalAirlocks(boolean externalAirlocks){
this.externalAirlocks = externalAirlocks;
}
public void comms(boolean comms){
this.comms = comms;
}
public void waterMaking(boolean waterMaking){
this.waterMaking = waterMaking;
}
public boolean[] getMachines(){
machines[0] = oxygenator;
machines[1] = nuclearReactor;
machines[2] = innerAirlocks;
machines[3] = externalAirlocks;
machines[4] = comms;
machines[5] = waterMaking;
return machines;
}
// Set machines to false
public void breakMachines(){
oxygenator(false);
nuclearReactor(false);
innerAirlocks(false);
externalAirlocks(false);
comms(false);
waterMaking(false);
map.clear();
initializeMap(map);
}
public void startMachines(){
// Set all of the booleans from this Facility to true;
// This booleans are what we call "the machines from the Facility"
oxygenator(true);
nuclearReactor(true);
innerAirlocks(true);
externalAirlocks(true);
comms(true);
waterMaking(true);
map.clear();
initializeMap(map);
}
public void initializeMap(Map<String, Boolean> map){
this.map.put("Oxygenator", oxygenator);
this.map.put("Inner Airlocks", innerAirlocks);
this.map.put("External Airlocks", externalAirlocks);
this.map.put("Nuclear Reactor", nuclearReactor);
this.map.put("Comms", comms);
this.map.put("WaterMaking", waterMaking);
}
public Map<String, Boolean> getMap(){
return map;
}
public void getFacilityStatus(){ // The status of the map in this object
for (Map.Entry<String, Boolean> i: map.entrySet()){
System.out.println(i.getKey() + ": " + i.getValue());
}
}
public void getFacilityStatus(Map<String, Boolean> map){ // The status of any Facility map
for (Map.Entry<String, Boolean> i: map.entrySet()){
System.out.println(i.getKey() + ": " + i.getValue());
}
}
}
Here is the StateMachine class:
public class StateMachine {
public State state = State.RESTING;
enum State {
WORKING, RESTING, MAINTENANCE, BROKEN
}
public State getFacilityState(){
return state;
}
public void setStateWorking(Facility fac){
fac.state = State.WORKING;
}
public void setStateResting(Facility fac){
fac.state = State.RESTING;
}
public void setStateMaintenance(Facility fac){
fac.state = State.MAINTENANCE;
}
public void setStateBroken(Facility fac) { fac.state = State.BROKEN;}
public State getState(){
return state;
}
}
In my Inspection class, I have two methods that have to check the state of the Facility to see if it's working, but I am having trouble with my if statement:
import java.util.*;
public class Inspection {
private Facility fac;
public boolean isBroken(){
if (fac.state == State.BROKEN)
return true;
else
return false;
}
public void makeMaintenanceRequest(Control c){
if (fac.state == State.BROKEN){
c.scheduleMaintenance(fac);
}
}
I want the methods to be able to compare the current state of a Facility to the Broken state. How should I compare the states? I keep getting the "cannot find symbol" error for State.BROKEN
Although I cannot understand very well what you're trying to do, I can tell you the Inspection class might already work as you'd like.
I see you commented out the constructor, why? It was okay to inject a Facility instance inside Inspection. However, you should accept a StateMachine instead.
public class Inspection {
private final StateMachine stateMachine;
public Inspection(final StateMachine stateMachine) {
this.stateMachine = stateMachine;
}
...
}
Then, inside your Inspection#isBroken method
public boolean isBroken() {
return this.stateMachine.getFacilityState() == State.BROKEN; // "this" not necessary
}
As Facility extends StateMachine, it exposes a getFacilityState() method.
And because Facility extends StateMachine, Inspection is able to accept it.
final Facility facility = new Facility(...);
final Inspection inspection = new Inspection(facility);
final boolean isBroken = inspection.isBroken();
A simple solution would be to replace State.BROKEN with StateMachine.State.BROKEN
public boolean isBroken(){
if (fac.state == StateMachine.State.BROKEN)
return true;
else
return false;
}
I'm trying to store a coordnates (array of double) using Realm-java,but I'm not able to do it.
Here is an example of json that I'm trying to parse:
{"_id":"597cd98b3af0b6315576d717",
"comarca":"string",
"font":null,
"imatge":"string",
"location":{
"coordinates":[41.64642,1.1393],
"type":"Point"
},
"marca":"string",
"municipi":"string",
"publisher":"string",
"recursurl":"string",
"tematica":"string",
"titol":"string"
}
My global object code is like that
public class Images extends RealmObject implements Serializable {
#PrimaryKey
private String _id;
private String recursurl;
private String titol;
private String municipi;
private String comarca;
private String marca;
private String imatge;
#Nullable
private Location location;
private String tematica;
private String font;
private String parentRoute;
public Location getLocation() {return location;}
public void setLocation(Location location) {this.location = location;}
public String getParentRoute() {
return parentRoute;
}
public void setParentRoute(String parentRoute) {
this.parentRoute = parentRoute;
}
public String get_id() {
return _id;
}
public void set_id(String _id) {
this._id = _id;
}
public String getFont() {
return font;
}
public void setFont(String font) {
this.font = font;
}
public String getRecursurl() {
return recursurl;
}
public void setRecursurl(String recursurl) {
this.recursurl = recursurl;
}
public String getTitol() {
return titol;
}
public void setTitol(String titol) {
this.titol = titol;
}
public String getMunicipi() {
return municipi;
}
public void setMunicipi(String municipi) {
this.municipi = municipi;
}
public String getComarca() {
return comarca;
}
public void setComarca(String comarca) {
this.comarca = comarca;
}
public String getMarca() {
return marca;
}
public void setMarca(String marca) {
this.marca = marca;
}
public String getImatge() {
return imatge;
}
public void setImatge(String imatge) {
this.imatge = imatge;
}
public String getTematica() {
return tematica;
}
public void setTematica(String tematica) {
this.tematica = tematica;
}
And Location is a composite of type and a realmlist
Location.java
public class Location extends RealmObject implements Serializable {
private String type;
private RealmList<RealmDoubleObject> coordinates;
public Location() {
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public RealmList<RealmDoubleObject> getCoordinates() {
return coordinates;
}
public void setCoordinates(RealmList<RealmDoubleObject> coordinates) {
this.coordinates = coordinates;
}
}
RealmDoubleObject.java
public class RealmDoubleObject extends RealmObject implements Serializable{
private Double value;
public RealmDoubleObject() {
}
public Double getDoublevalue() {
return value;
}
public void setDoublevalue(Double value) {
this.value = value;
}
}
The error is com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was NUMBER at path $[0].location.coordinates[0] but I'm not able to figure out why this number is not "fitting" by RealmDoubleObject.
For those that not familiar with realm RealmList doesn't work and you have to build your own realm object.
Thank you. I hope to find some Realm experts here!
SOLVED:
using Gson deserializer it can be done
First we have to initialize the gson object like this
Gson gson = new GsonBuilder()
.setExclusionStrategies(new ExclusionStrategy() {
#Override
public boolean shouldSkipField(FieldAttributes f) {
return f.getDeclaringClass().equals(RealmObject.class);
}
#Override
public boolean shouldSkipClass(Class<?> clazz) {
return false;
}
})
.registerTypeAdapter(new TypeToken<RealmList<RealmDoubleObject>>() {}.getType(), new TypeAdapter<RealmList<RealmDoubleObject>>() {
#Override
public void write(JsonWriter out, RealmList<RealmDoubleObject> value) throws IOException {
// Ignore
}
#Override
public RealmList<RealmDoubleObject> read(JsonReader in) throws IOException {
RealmList<RealmDoubleObject> list = new RealmList<RealmDoubleObject>();
in.beginArray();
while (in.hasNext()) {
Double valor = in.nextDouble();
list.add(new RealmDoubleObject(valor));
}
in.endArray();
return list;
}
})
.create();
And then we have to put some other constructor method
public RealmDoubleObject(double v) {
this.value = v;
}
and this is all.
Thanks for the help #EpicPandaForce
I have just recently learned about setter , getters and this.(somthing).
I having quite a hard time undersatnding when to use getters and when to use setters .
Another thing , can i use setter method to print out ?
For Example :
class workerId {
private int workerAge;
private String workerName;
private int workerIde;
public void setWorkerAge(int newAge) {
newAge = workerAge;
}
public void setWorkerName(String newName) {
newName = workerName;
}
public int setIde(int ide) {
ide = workerIde;
return ide;
}
}
public class App {
public static void main(String[] args) {
workerId worker1 = new workerId();
worker1.setWorkerAge(41);
worker1.setWorkerName("dan ");
worker1.setIde(318574524);
System.out.println(worker1.setIde());
}
}
the system out print shows an error and i didnt understand why , is it because only getters can be used in the sysout command ?
No offense intended, but your setters are all wrong. You should assign your properties to the values passed in the setter, not setting the value again. So your code should look like this:
class workerId {
private int workerAge;
private String workerName;
private int workerIde;
public void setWorkerAge(int newAge) {
workerAge = newAge;
}
public void setWorkerName(String newName) {
workerName = newName;
}
public int setIde(int ide) {
workerIde = ide;
}
}
If you need getters, it should look like this:
class workerId {
private int workerAge;
private String workerName;
private int workerIde;
public void setWorkerAge(int newAge) {
workerAge = newAge;
}
public void setWorkerName(String newName) {
workerName = newName;
}
public int setIde(int ide) {
workerIde = ide;
}
public int getIde() {
return workerIde;
}
}
Then you can print, e.g. System.out.println(worker1.getIde());
You should be using a getter method to get the values.
class workerId {
private int workerAge;
private String workerName;
private int workerIde;
public void setWorkerAge(int newAge) {
workerAge = newAge;
}
public void setWorkerName(String newName) {
workerName=newName;
}
public int getIde() {
return workerIde;
}
public void setIde(int ide) {
workerIde = ide;
}
}
public class App {
public static void main(String[] args) {
workerId worker1 = new workerId();
worker1.setWorkerAge(41);
worker1.setWorkerName("dan ");
worker1.setIde(318574524);
System.out.println(worker1.getIde());
}
}
class workerId {
private int workerAge;
private String workerName;
private int workerIde;
public void setWorkerAge(int newAge) {
this.workerAge = newAge;
}
public void setWorkerName(String newName) {
this.workerName = newName;
}
public int setIde(int ide) {
this.workerIde = ide;
return this.workerIde;
}
}
public class Car {
public static void main(String[] args) {
workerId worker1 = new workerId();
worker1.setWorkerAge(41);
worker1.setWorkerName("dan ");
worker1.setIde(318574524);
System.out.println(worker1.setIde(56));
}
}
I am very new to JSON and jackson, currently I have pojo files and I am trying to get the data and store it in an array. for example I want to extract Network name and store it an array and later display or compare it with live site data.

The reason is that you're using a regular List interface for your list of networks instead of the generic version with the bounds for the expected type.
Try changing the field declaration from:
private List networks;
to
private List<Networks> networks;
While you're at it, it looks like you're using the regular List interface pretty much everywhere. You'll probably run into more issues if you don't convert them all to include the type you expect in the list.
Essentially, you're not providing enough information about the type of object you expect in the list for jackson to figure out what to populate it with. You can read more about generics here: http://docs.oracle.com/javase/tutorial/extra/generics/intro.html
EDIT:
It looks (from your comment) that you've already tried disabling checks for unknown properties, but try adding this annotation to your Networks class:
#JsonIgnoreProperties(ignoreUnknown = true)
public class Table{
private String column[];
private String dataType[];
private boolean PK[];
private boolean NN[];
private int count;
public Table()
{
count =0;
}
public void AddColumn(String name,String dtype,boolean pk,boolean nn)
{
column[count]=name;
dataType[count]=dtype;
PK[count]=pk;
NN[count]=nn;
count++;
}
public void Display(Table T)
{
}
public void DeleteColumn(String name)
{
if(count==0){return;}
else if(count ==1)
{
if(name==column[0])
column[0]=null;
dataType[0]=null;
count--;
return;
}
else
for(int i=0;i<count;i++)
{
if(name==column[i])
{
column[i]=column[count-1];
dataType[i]=dataType[count-1];
PK[i]=PK[count-1];
NN[i]=NN[count-1];
}
}
}
This is my table class; as im designing an Entity table and for keeping column Name data type etc. Is this class and its private attributes correct or should i break this into more classes eg attributes.
I think that you should create Column class.
I will do it in this way (of course it can be done better):
public class DataType {
public static String DATA_TYPE_1 = "dataType1";
public static String DATA_TYPE_2 = "dataType2";
public static String DATA_TYPE_3 = "dataType3";
}
public class Column() {
private String name;
private DataType dataType;
private boolean PK;
private boolean NN;
// getters and setters
}
public class Table {
private ArrayList<Column> columns;
public Table() {
columns = new ArrayList<Column>();
}
public boolean AddColumn(Column column) {
columns.add(column);
}
public boolean DeleteColumn(String name) {
for (Column c : columns) {
if (c.getName().equals(name)) {
return columns.remove(column);
}
}
return false;
}
}
