JavaFX: ComboBox: Set a value to the combo box

By default, ComboBox widget do not set a value. If you want to set any default value to ComboBox, use 'setValue' method.

Ex

ObservableList<String> hobbies = FXCollections.observableArrayList("Tennis", "Football", "Cricket", "CoCO", "Rugby", "kabaddy");

ComboBox<String> hobbiesComboBox = new ComboBox<>(hobbies);

hobbiesComboBox.setVisibleRowCount(3);

hobbiesComboBox.setValue("Cricket");

ComboBoxApp.java

import javafx.application.Application;
