JavaFX | DatePicker with examples

DatePicker is a part of the JavaFX package, DatePicker allows to select the date from the popup calendar or type the text manually in the text field of date-picker.

Constructor of the DatePicker class are :

1. DatePicker():Creates a default DatePicker instance with a null date value set.
2. DatePicker(LocalDate l):Creates a DatePicker instance and sets the value to the given date.

Commonly used methods:

Below programs illustrate the DatePicker Class:

1. Program to create a date picker and display it in stage: This program creates a Date Picker indicated by the name d. The DatePicker will be created inside a scene, which in turn will be hosted inside a stage. The function setTitle() is used to provide title to the stage. Then a tile pane is created, on which addChildren() method is called to attach the button inside the scene. Finally, the show() method is called to display the final results.

   
   

   
   
   

   // Java Program to create a date picker // and display it in stage import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.layout.*; import javafx.event.ActionEvent; import javafx.event.EventHandler; import javafx.scene.control.*; import javafx.stage.Stage; import javafx.scene.control.Alert.AlertType; import java.time.LocalDate; public class date_picker_1 extends Application {        // launch the application     public void start(Stage s)     {         // set title for the stage         s.setTitle("creating date picker");            // create a tile pane         TilePane r = new TilePane();            // create a date picker         DatePicker d = new DatePicker();            // add button and label         r.getChildren().add(d);            // create a scene         Scene sc = new Scene(r, 200, 200);            // set the scene         s.setScene(sc);            s.show();     }        public static void main(String args[])     {         // launch the application         launch(args);     } }

   Output:
   

2. Program to create a date picker and create a label to show the date: This program creates a DatePicker indicated by the name d. The Date Picker will be created inside a scene, which in turn will be hosted inside a stage. We would create a label to show which date is choosed. The function setTitle() is used to provide title to the stage. Then a tile pane is created, on which addChildren() method is called to attach the button and label inside the scene. Finally, the show() method is called to display the final results.we would create an event handler to handle the date picker events. The event handler would be added to the button using setOnAction() function.The setShowWeekNumbers() will set the date picker to show week number of respective weeks.

   
   

   
   
   

   // Java Program to create a date picker // and create a label to show the date import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.layout.*; import javafx.event.ActionEvent; import javafx.event.EventHandler; import javafx.scene.control.*; import javafx.stage.Stage; import javafx.scene.control.Alert.AlertType; import java.time.*; import java.time.chrono.*; public class date_picker_2 extends Application {        // launch the application     public void start(Stage s)     {         // set title for the stage         s.setTitle("creating date picker");            // create a tile pane         TilePane r = new TilePane();            // label to show the date         Label l = new Label("no date selected");            // create a date picker         DatePicker d = new DatePicker();            // action event         EventHandler<ActionEvent> event = new EventHandler<ActionEvent>() {             public void handle(ActionEvent e)             {                 // get the date picker value                 LocalDate i = d.getValue();                    // get the selected date                 l.setText("Date :" + i);             }         };            // show week numbers         d.setShowWeekNumbers(true);            // when datePicker is pressed         d.setOnAction(event);            // add button and label         r.getChildren().add(d);         r.getChildren().add(l);            // create a scene         Scene sc = new Scene(r, 200, 200);            // set the scene         s.setScene(sc);            s.show();     }        public static void main(String args[])     {         // launch the application         launch(args);     } }

   Output:
