I have created three entity classes whose relation is defined as follows:
Screen -----> has many ConfigurableRows
ConfigurableRows -----> Has many Seats.
When i am trying to persist the Screen Class object no table is getting creating.
I am attaching my entity classes here.
public class Screen {

private String screenName;
#OneToMany(targetEntity=ConfigurableRow.class, mappedBy="screenid", fetch=FetchType.LAZY,cascade= CascadeType.ALL)

I am new to hibernate. Kindly let me know what I am doing wrong here.
My Tables are getting created now . But with out any values. Hence foreign key violation error is coming.
I think that is a OneToMany bidirectional relationship so
in the class ConfigurableRow you have to add an object from Screen class with annotation #ManyToOne
#ManyToOne
private Screen screen
i think you should put the onetomany annotation before your getrows() method.
#OneToMany(targetEntity=ConfigurableRow.class, mappedBy="screenid", fetch=FetchType.LAZY,cascade= CascadeType.ALL)
public List<ConfigurableRow> getRows() {
return rows;
}

I have tough problem with my project. Its hard to explain. I have two different model but, I should compare these two model. Should I make a new model for this two models?
Here is Cart.java. There is Voyage.java as a Model. This class differentiate if type_voyage not equals each other. I have another model named Bus.java. I should compare if it equals together with model.
Cart.java

When you remove all the code from your question that is superfluous, it makes the problem more obvious.
First I simplified your comparison method:
Cart.java
boolean cartContainsDifferentTypeVoyage(final String type_voyage) {
for(Voyage voyage : voyages) {
if(!type_voyage.equals(voyage.getType_voyage()) {
return true;
}
}
}
Then created an interface
interface Voyage {
String getType_voyage();
}
Bus.java
public class Bus implements Voyage {
...
private String type_voyage;
#Override
public String getType_voyage() {
return type_voyage;
}
...
}
And changed Voyage.java to Ferry.java
public class Ferry implements Voyage {
...
private String type_voyage;
...
#Override
public String getType_voyage() {
return type_voyage;
}
...
}
You may want to look at creating some more classes so that your 'model' classes are not doing to much / have so many responsibilities.

#Override

Now the problem is the dropdown is not showing up. Whereas if I try the same autocompletetextview with array adapter, its showing up.
Here is the activity part I am calling the api from:
autoCompleteTextViewSearch.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
if (charSequence.toString().length() > 0) {
hitSearchAPI(charSequence.toString());
}
}
#Override
public void afterTextChanged(Editable editable) {
}
});
On API response:
final GsonBuilder gsonBuilder = new GsonBuilder();
final Gson gson = gsonBuilder.create();
productList = gson.fromJson(responseString, ProductListModel[].class);
arrayListProducts = new ArrayList<ProductListModel>(Arrays.asList(productList));
productsSearchAdapter = new ProductSearchAdapter(MainActivity.this, arrayListProducts);
autoCompleteTextViewSearch.setThreshold(1);
autoCompleteTextViewSearch.setAdapter(productsSearchAdapter);
Same textview working with array adapter but not with custom adapter.

You need to add toString() method to your model so the AutoCompleteTextView can compare between the typed String and the returned value.
if you are looking by name the toString() needs to return it :
#Override
public String toString() {
return name ;
}
}
In the below android activity, trying to display data in a view pager and it is working as expected.
But in loadItemsForSuppliers method, when i am adding SupplierAndItemList object to it's arraylist, value returned from getInventoriesByItemDetails method is not updating properly rather takes last value always.

I have go through your method I have found some assigning value issue
private void loadItemsForSuppliers() {
for (Dealer dealer : supplierList) {
ArrayList<ItemDetail> inventories = new ArrayList<>();
SupplierAndItemList supplierAndItem = new SupplierAndItemList();
supplierAndItem.setDealerName(dealer.getDealerName());
supplierAndItem.setSelectedItemList(getInventoriesByItemDetails(dealer, inventories));
supplierAndItemLists.add(supplierAndItem);
}
}
private ArrayList<ItemDetail> getInventoriesByItemDetails(Dealer dealer, ArrayList<ItemDetail> inventories) {
for (ItemDetail id : itemDetails) {
DealerInventory dealerInventory = new DealerInventory();
dealerInventory = dealerInventory.getLastModifiedInventory(this, id.getItemId(), dealer.getId());
if (dealerInventory != null) {
if (dealerInventory.getQuantity() >= 0) {
id.setParentSalesPointLastStock(String.valueOf(dealerInventory.getQuantity()));
id.setParentSalesPointLastStockTakingDate(dealerInventory.getStockTakingDate());
}
} else {
id.setParentSalesPointLastStock(UiConstants.NA);
id.setParentSalesPointLastStockTakingDate(UiConstants.NA);
}
inventories.add(id); // do this
}
return inventories; // you are not assigning value anywhere;
}
You are not assigning value to the inventories in getInventoriesByItemDetails. I think you should add item through inventories.add(id);
Check it , Hope this help

I am trying to sort the category arraylist with Collections.sort method but have no luck with it.
Here is my code:
public class Categories implements Parcelable {
private ArrayList<Category> category;
private Recent recent;
public ArrayList<Category> getCategories() {
return this.category;
}
public void setCategory(ArrayList<Category> category) {
this.category = category;
}
public Recent getRecent() {
return this.recent;
}
public void setRecent(Recent recent) {
this.recent = recent;
}
protected Categories(Parcel in) {
if (in.readByte() == 0x01) {
category = new ArrayList<Category>();
in.readList(category, Category.class.getClassLoader());
} else {
category = null;
}
recent = (Recent) in.readValue(Recent.class.getClassLoader());
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
if (category == null) {
dest.writeByte((byte) (0x00));
} else {
dest.writeByte((byte) (0x01));
dest.writeList(category);
}
dest.writeValue(recent);
}
public static final Parcelable.Creator<Categories> CREATOR = new Parcelable.Creator<Categories>() {
#Override
public Categories createFromParcel(Parcel in) {
return new Categories(in);
}
#Override
public Categories[] newArray(int size) {
return new Categories[size];
}
};
}
You can also use custom comparator:
public class CategoriesComparator implements Comparator<Category> {
#Override
public int compare(Category category1, Category category2) {
return category1.getSomeProperty().compareTo(category2.getSomeProperty());
}
}
When you want to compare call this:
Collections.sort(yourListCategories, new CategoriesComparator());
Hope it helps!
Collections.sort(yourListHere,new Comparator<Categories>() {
#Override
public int compare(Categories lhs, Categories rhs) {
//your sort logic here
return 0;
}
});
Hope this helps.
I'm trying to create an implementation of TransformList that maintains a list of distinct values off a source list. However, I'm a little puzzled on how the implementation should add the distinct values to my hashmap and distinct list that are contained internally. I think my ListChangeListener.change should work though. But how do I intercept any new or removed distinct values and add/remove them to the distinct map and list?
public class DistinctList<E> extends TransformationList<E,E> {
private final ObservableList<E> distinctList = FXCollections.observableArrayList();
private final ConcurrentHashMap<E,E> distinctValues = new ConcurrentHashMap<>();
private final ObservableList<E> source;
public DistinctList(ObservableList<E> source) {
super(source);
this.source = source;
source.stream().filter(s -> attemptAdd(s)).forEach(s -> distinctList.add(s));
}
private boolean attemptAdd(E e) {
final boolean result = distinctValues.putIfAbsent(e,e) == null;
if (result) {
distinctList.add(e);
}
return result;
}
private boolean attemptRemove(E e) {
final boolean result = distinctValues.remove(e, e);
if (result) {
distinctList.remove(e);
}
return result;
}
#Override
protected void sourceChanged(ListChangeListener.Change<? extends E> c) {
fireChange(new ListChangeListener.Change<E>(this) {
#Override
public boolean wasAdded() {
if (c.getAddedSubList().stream().filter(v -> distinctValues.contains(v) == false).findAny().isPresent()) {
return true;
}
else {
return false;
}
}
#Override
public boolean wasRemoved() {
if (c.getRemoved().stream().filter(v -> !source.contains(v)).findAny().isPresent()) {
return true;
}
else {
return false;
}
}
#Override

}
#Override

}
#Override

}
#Override

UPDATE
I kept working with this and I think I figured out where to interact source changes with the distinct value map and list. But when my source list removes a value (and other values with same hashcode/equals still exists), it wrongly removes the value from the distinct values. What am I doing wrong?
public class DistinctList<E> extends TransformationList<E,E> {
private final ObservableList<E> distinctList = FXCollections.observableArrayList();

super(source);
this.source = source;
source.stream().forEach(s -> attemptAdd(s));
}
private boolean attemptAdd(E e) {
final boolean result = distinctValues.putIfAbsent(e,e) == null;
if (result) {
distinctList.add(e);
}
return result;
}
private boolean attemptRemove(E e) {
final boolean result = distinctValues.remove(e, e);
if (result) {
distinctList.remove(e);
}
return result;
}
#Override

while (c.next()) {
