Try to put some order on your code because is not easy read it. Also, create a method where you can inicialite your widgets, something like this:
public static void startCom(){
text1 = (textView) findById....
.
.
.
}
Only on the method onCreate you invoke startComp, just to save the order of the code.

How you save an Array from TMDB to SQLite

let's get straight. I want to build an movie app which have popular and kid, when data's liked, it store in SQLite. So in layout favorited, i make 2 layout, popular and kid. To distribute the data, i used clause category : movie and genre_ids : 16 / not. But when i test my app (previously i reinstall it, like suggestion in this site) and liked the movie, in logcat show something like this :
2019-10-11 09:24:05.941 5582-5582/com.example.apkfin5 E/SQLiteDatabase: Error inserting overview=blablabla. backdroppath=/n6bUvigpRFqSwmPp1m2YADdbRBc.jpg release_date=2019-10-02 [genre_ids]=null posterpath=/udDclJoHjfjb8Ekgsd4FDteOkCU.jpg id=475557 title=Joker category=movie

You can see that the genre_ids is null, and i set my app, when data's null, data will not distribute to SQLite. So why i can't get the genre_ids ?
For support the diagnose, here's my dbHelper :
public class DbHelper extends SQLiteOpenHelper {

This's my first time assigment to build with two different view from 1 API. So ya, i got a little confused here. Thank for the answer.
i've been realized that i need to deserialized this list : genre_id, so guys, can you tell me how to deserialized "genre_ids": [
99,
10402
]
is it use Class List, then the value just Public int id ? or i need more id ? cause some genre_ids have more than one int.

So, i try to solve with deserialized, but i didn't understand how to implement with that data to the database.
And the best i can do was make another database for save data when it clicked. Before that, i build another request from the web so i can get data only from kid. Make sure that the other request didn't get data, set the request with "without_genres", i'm using tmdb btw. That need because you don't want duplicate kid's datas from reguler movie and kid show in tab favorite. Furthermore, i used that database to make widget. So you don't want your 2 widget (reguler and kid) have similiar movie kid in both of it.

SQLite db file not found on Android

If you don't specify any path, it will be stored in databases folder of your application directory.

Return more that one ArrayList

I'm trying to deal with this baking JSON:
in android app so this is the class to bring the JSON data from link:
OpenBakingJsonUtils.java:
public final class OpenBakingJsonUtils {
public static ArrayList<ArraysLists> getSimpleBakingStringsFromJson(Context context, String bakingJsonString)
throws JSONException {
final String ID = "id";
final String NAME = "name";
final String SERVINGS = "servings";
final String INGREDIENTS = "ingredients";
final String STEPS = "steps";
final String QUANTITY = "quantity";
final String MEASURE = "measure";
final String INGREDIENT = "ingredient";
final String IDSTEPS = "id";
final String SHORTDESCRIPTION = "shortDescription";
final String DESCRIPTION = "description";
final String VIDEOURL = "videoURL";
final String THUMBNAILURL = "thumbnailURL";
ArrayList<ArraysLists> parsedRecipeData = new ArrayList<ArraysLists>();
ArrayList<BakingItem> Baking = new ArrayList<BakingItem>();
JSONArray recipeArray = new JSONArray(bakingJsonString);
for (int i = 0; i < recipeArray.length(); i++) {
int id;
String name;
int servings;
double quantity;
String measure;
String ingredient;
int idSteps;
String shortDescription;
String description;
String videoURL;
String thumbnailURL;
JSONObject recipeObject = recipeArray.getJSONObject(i);
id = recipeObject.getInt(ID);
name = recipeObject.getString(NAME);
servings = recipeObject.getInt(SERVINGS);
ArrayList<IngredientsItem> Ingredients = new ArrayList<IngredientsItem>();
JSONArray ingredientsArray = recipeObject.getJSONArray(INGREDIENTS);
for(int j = 0 ; j< ingredientsArray.length(); j++) {
JSONObject ingredientsObject = ingredientsArray.getJSONObject(j);
quantity = ingredientsObject.getDouble(QUANTITY);
measure = ingredientsObject.getString(MEASURE);
ingredient = ingredientsObject.getString(INGREDIENT);
Ingredients.add(new IngredientsItem(quantity, measure, ingredient));
}
ArrayList<StepsItem> Steps = new ArrayList<StepsItem>();
JSONArray stepsArray = recipeObject.getJSONArray(STEPS);
for(int j = 0 ; j< stepsArray.length(); j++) {
JSONObject stepsObject = stepsArray.getJSONObject(j);
idSteps = recipeObject.getInt(IDSTEPS);
shortDescription = stepsObject.getString(SHORTDESCRIPTION);
description = stepsObject.getString(DESCRIPTION);
videoURL = stepsObject.getString(VIDEOURL);
thumbnailURL = stepsObject.getString(THUMBNAILURL);
Steps.add(new StepsItem(idSteps, shortDescription, description, videoURL, thumbnailURL));
}
Baking.add(new BakingItem(id, name, servings, Ingredients, Steps));
parsedRecipeData.add(new ArraysLists(Baking, Ingredients, Steps));
}
return parsedRecipeData;
}
}
as you see there are 3 ArrayList classes:
ArrayList<BakingItem>
ArrayList<IngredientsItem>
ArrayList<StepsItem>
and this is the code for each one:
BakingItem.java:
public class BakingItem implements Parcelable {
private int id;
private String name;
private int servings;
private ArrayList<IngredientsItem> ingredients = new ArrayList<IngredientsItem>();
private ArrayList<StepsItem> steps = new ArrayList<StepsItem>();
public BakingItem(int id, String name, int servings, ArrayList<IngredientsItem> ingredients, ArrayList<StepsItem> steps) {
this.id = id;
this.name = name;
this.servings = servings;
this.ingredients = ingredients;
this.steps = steps;
}
#Override
public void writeToParcel(Parcel out, int flags) {
out.writeInt(id);
out.writeString(name);
out.writeInt(servings);
out.writeTypedList(ingredients);
out.writeTypedList(steps);
}
private BakingItem(Parcel in) {
this.id = in.readInt();
this.name = in.readString();
this.servings = in.readInt();
ingredients = new ArrayList<IngredientsItem>();
in.readTypedList(ingredients, IngredientsItem.CREATOR);
}
public BakingItem() {
}
#Override
public int describeContents() {
return 0;
}
public static final Parcelable.Creator<BakingItem> CREATOR = new Parcelable.Creator<BakingItem>() {
#Override
public BakingItem createFromParcel(Parcel in) {
return new BakingItem(in);
}
#Override
public BakingItem[] newArray(int i) {
return new BakingItem[i];
}
};
public int getId() {
return id;
}
public String getName() {
return name;
}
public int getServings() {
return servings;
}
}
IngredientsItem.java:
public class IngredientsItem implements Parcelable {
private double quantity;
private String measure;
private String ingredient;
public IngredientsItem(double quantity, String measure, String ingredient) {
this.quantity = quantity;
this.measure = measure;
this.ingredient = ingredient;
}
#Override
public void writeToParcel(Parcel out, int flags) {
out.writeDouble(quantity);
out.writeString(measure);
out.writeString(ingredient);
}
private IngredientsItem(Parcel in) {
this.quantity = in.readDouble();
this.measure = in.readString();
this.ingredient = in.readString();
}
public IngredientsItem() {
}
#Override
public int describeContents() {
return 0;
}
public static final Parcelable.Creator<IngredientsItem> CREATOR = new Parcelable.Creator<IngredientsItem>() {
#Override
public IngredientsItem createFromParcel(Parcel in) {
return new IngredientsItem(in);
}
#Override
public IngredientsItem[] newArray(int i) {
return new IngredientsItem[i];
}
};
public double getQuantity() {
return quantity;
}
public String getMeasure() {
return measure;
}
public String getIngredient() {
return ingredient;
}
}
as well as the StepsItem class
and the forth is the ArraysLists.java which contain all the 3 arrays above and returned by the OpenBakingJsonUtils.java:
Then I'm trying to call these JSON data in different activities
so in MainActivity.java in loadInBackground:
Override
public ArrayList<BakingItem> loadInBackground() {
URL recipeRequestUrl = NetworkUtils.buildUrl();
try {
String jsonBakingResponse = NetworkUtils.getResponseFromHttpUrl(recipeRequestUrl);
ArrayList<ArraysLists> simpleJsonBakingData = OpenBakingJsonUtils.getSimpleBakingStringsFromJson(MainActivity.this, jsonBakingResponse);
return simpleJsonBakingData;
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
I call the returned ArrayList from OpenBakingJsonUtils.java which is in this case the ArraysLists,
then in DetailActivity.java in doInBackground:
#Override
protected ArrayList<ArraysLists> doInBackground(Object... params) {
if (params.length == 0) {
return null;
}
URL reviewsRequestUrl = NetworkUtils.buildUrl();
try {
String jsonReviewResponse = NetworkUtils.getResponseFromHttpUrl(reviewsRequestUrl);
ArrayList<ArraysLists> simpleJsonReviewData = OpenBakingJsonUtils.getSimpleBakingStringsFromJson(DetailsActivity.this, jsonReviewResponse);
return simpleJsonReviewData;
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
here I call the ArrayList of ArraysLists too but the problem in adapters of MainActivity.java and DetailsActivity.java in onBindViewHolder:
holder.CommentContent.setText(String.valueOf(mCommentsItems.get(position).getQuantity()));
it just says that cannot resolve method getQuantity() which is in IngredientsItem.java while I used the ArraysLists.java that returned by OpenBakingJsonUtils.java
so what should I do to call methods from BakingItem.java and IngredientsItem.java while I use the returned ArraysLists.java ?

How can I create a instance of a class with an array of Strings as the only instance variable?

I have written a class Form. An array of 10 Strings is the only parameter in the constructor. How can I create an instance of the class? I'm sure there are other problems in my setters and getters but I cant test them until I fix this.
public class FormLab {
public static void main(String[]args){
Form f1 = new Form(String webForm);
System.out.println(print(String[] webForm));
System.out.println("Any Empty Strings? " + f1.getEmptyFields);
System.out.println("Number of characters in userID? " + f1.getCharNum);
System.out.println("Do password fields match? " + f1.getPwCheck);
System.out.println("Does email contain correct characters? " + f1.getEmailCheck);
}
}
public class Form {
String[] webForm = new String[10];
private String userID;
private String pw;
private String pw2;
private String email;
private String name;
private String address;
private String city;
private String state;
private String zip;
private String telephone;
//constructor
public Form(String[] webForm){
//filling array with field values
webForm[0] = "0123456789";
webForm[1] = "java123";
webForm[2] = "java123";
webForm[3] = "luke.skywalker#jedi.com";
webForm[4] = "Luke Skywalker";
webForm[5] = "1234 The Force Way";
webForm[6] = "Rome";
webForm[7] = "GA";
webForm[8] = "30161";
webForm[9] = "7065551234";
}
public boolean getEmptyFields() {
//boolean empty = false;
for(int i = 0; i < webForm.length; i++){
if(webForm[i]!= null){
return true;
}
}
return false;
}
public String getUserID(){
return userID;
}
public void setUserId(String userID){
this.userID = userID;
}
public String getPw(){
return pw;
}
public void setPw(String pw){
this.pw = pw;
}
public String getPw2(){
return pw2;
}
public void setPw2(String pw2){
this.pw2 = pw2;
}
public String getEmail(){
return email;
}
public void setEmail(String email){
this.email = email;
}
public String getName(){
return name;
}
public void setName(String name){
this.name = name;
}
public String getAddress(){
return address;
}
public void setAddress(String address){
this.address = address;
}
public String getCity(){
return city;
}
public void setCity(String city){
this.city = city;
}
public String getState(){
return state;
}
public void setState(String state){
this.state = state;
}
public String getZip(){
return userID;
}
public void setZip(String zip){
this.zip = zip;
}
public String getTelephone(){
return telephone;
}
public void setTelephone(String telephone){
this.telephone = telephone;
}
public int getCharNum(String userID) {
int userLength = 0;
//userID.length();
return userLength;
}
public boolean getPwCheck() {
boolean check = pw.equalsIgnoreCase(pw2);
// pw.equalsIgnoreCase(pw2);
return check;
}
public boolean getEmailCheck(String email) {
if(email.contains("#") && email.contains(".")){
return true;
}
return false;
}
public static void getPrint(String[] webForm) {
System.out.println(webForm.toString());
}
}

Use method arraycopy.
public Form(String[] webForm){
System.arraycopy(webForm, 0, this.webForm, 0, webForm.length);
}

The constructor takes a string array as argument, but you are passing it a string, try:
myList = new String[];
myForm = new Form(myList);

You need to declare your array before putting it as a parameter as follow:
public class FormLab {
public static void main(String[]args){
String webForm = new String[10];
Form f1 = new Form(webForm);
/*System.out.println(print(String[] webForm)); THIS IS WRONG*/
/*TO PRINT THE VALUES IN THE ARRAY YOU NEED TO WRITE A METHOD IN UR
FORM CLASS THAT WILL LOOP THRU UR VARIABLE AND PRINT*/
System.out.println("Any Empty Strings? " + f1.getEmptyFields);
System.out.println("Number of characters in userID? " + f1.getCharNum);
System.out.println("Do password fields match? " + f1.getPwCheck);
System.out.println("Does email contain correct characters? " + f1.getEmailCheck);
}

Can't get ComboboxTableCell in javafx app

I am trying to show a combobox for each record that is fetched from database,but unfortunatley i can't get any combobox in expected column.
Here is code for my model class:
public class Employee {
private final int id;
private final SimpleStringProperty ename;
private final SimpleStringProperty ecnic;
private final SimpleDoubleProperty ebalance;
private final SimpleDoubleProperty etotalpaid;
private SimpleStringProperty estatus;
public Employee(int id, String ename, String ecnic, Double ebalance,
Double etotalpaid, String estatus) {
super();
this.id = id;
this.ename = new SimpleStringProperty(ename);
this.ecnic = new SimpleStringProperty(ecnic);
this.ebalance = new SimpleDoubleProperty(ebalance);
this.etotalpaid = new SimpleDoubleProperty(etotalpaid);
this.estatus = new SimpleStringProperty(estatus);
}
public String getEstatusproperty() {
return estatus.get();
}
public String getEstatus() {
return estatus.get();
}
public void setEstatus(String estatus) {
this.estatus = new SimpleStringProperty(estatus);
}
public int getId() {
return id;
}
public String getEname() {
return ename.get();
}
public String getEcnic() {
return ecnic.get();
}
public Double getEbalance() {
return ebalance.get();
}
public Double getEtotalpaid() {
return etotalpaid.get();
}
}
Here is code for my method that i call to fetch data from database..
public void attendence() throws SQLException{
employeelist = FXCollections.observableArrayList();
ename.setCellValueFactory(new PropertyValueFactory<Employee,String>("ename"));
ecnic.setCellValueFactory(new PropertyValueFactory<Employee,String>("ecnic"));
ebalance.setCellValueFactory(new PropertyValueFactory<Employee,Double>("ebalance"));
etotalpaid.setCellValueFactory(new PropertyValueFactory<Employee,Double>("etotalpaid"));
estatus.setCellValueFactory(new PropertyValueFactory<Employee,String>("estatus"));
estatus.setCellFactory(ComboBoxTableCell.forTableColumn(new DefaultStringConverter(), attendenceoptions));
estatus.setOnEditCommit(
new EventHandler<CellEditEvent<Employee, String>>() {
#Override
public void handle(CellEditEvent<Employee, String> t) {
((Employee) t.getTableView().getItems().get(t.getTablePosition().getRow())).setEstatus(t.getNewValue());
};
});
estatus.setEditable(true);
stmt = conn.createStatement();
sql = "select * from employe";
rs = stmt.executeQuery(sql);
while(rs.next()){
employeelist.add(new Employee(rs.getInt(1),rs.getString(2),rs.getString(3),rs.getDouble(5),rs.getDouble(6),"Present"));
employeetable.setItems(employeelist);
}
stmt.close();
rs.close();
}
}

Added this in method to solve issue.
employeetable.setEditable(true);
