When showing, you can see the list of choices in a choice box and while not showing, it displays the current choice. By default, no option is selected in a choice box.In JavaFX a choice box is represented by the class javafx.scene.control.ChoiceBox. You can create a choice box by instantiating this class.This class has a property named items, it is of the type ObservableList and it holds the list of choices to ... Read More
The text field accepts and displays the text. In the latest versions of JavaFX, it accepts only a single line.Similar to the text field a password field accepts text but instead of displaying the given text, it hides the typed characters by displaying an echo string.In JavaFX the javafx.scene.control.PasswordField represents a password field and it inherits the Text class. To create a password field you need to instantiate this class.This class inherits a property named text from its superclass TextInputControl. This property holds the contents of the current password field. You can retrieve this data using the getText() method.Exampleimport javafx.application.Application; import ... Read More

You can display a text element/image on the User Interface using the Label component. It is a not editable text control, mostly used to specify the purpose of other nodes in the application.In JavaFX, you can create a label by instantiating the javafx.scene.control.Label class. To create a label, you need to instantiate this class.Once you have created a label, you can set the maximum width and height of it using the setMaxWidth() and setMaxHeight() methods respectively.Once you set the maximum with of a label the contents of it exceeding the specified the width will be chopped off.To avoid this you ...

Suppose we have two arrays arr1 and arr2, the elements of arr2 are unique, and all elements in arr2 are also present in arr1. We have to sort the elements of arr1 in such a way that the relative ordering of items in arr1 are the same as in arr2. If there are some elements that are not present in arr2, they should be placed at the end of arr1 in ascending order. So if the arr1 is like [2, 3, 1, 3, 2, 4, 6, 7, 9, 2, 19], and arr2 is like [2, 1, 4, 3, 9, 6], ... Read More
