JavaFX FileChooser

JavaFX File chooser enables users to browse the files from the file system. javafx.stage.FileChooser class represents FileChooser. It can be created by instantiating FileChooser class. It contains two main methods.

As we see in the modern day applications, there are two types of dialogues shown to the user, one is for opening the file and the other is for saving the files. In each case, the user needs to browse a location for the file and give the name to the file.

The FileChooser class provides two types of methods,

showOpenDialog()
showSaveDialog()

The following code implements showSaveDialog() method.

Example 1:

  package application;  import javafx.application.Application;  import javafx.scene.Scene;  import javafx.scene.control.Button;  import javafx.scene.control.Label;  import javafx.scene.control.TextField;  import javafx.scene.layout.HBox;  import javafx.stage.FileChooser;  import javafx.stage.Stage;  public class FileChooserExample extends Application{    @Override  public void start(Stage primaryStage) throws Exception {  // TODO Auto-generated method stub    FileChooser file = new FileChooser();  file.setTitle(“Open File”);  file.showOpenDialog(primaryStage);    HBox root = new HBox();    root.setSpacing(20);    Scene scene = new Scene(root,350,100);  primaryStage.setScene(scene);  primaryStage.setTitle(“FileChooser Example”);  primaryStage.show();    }  public static void main(String[] args) {  launch(args);  }    }    

The above code shows the following dialogue box to the user where user is prompted to browse the location of the file which needs to be opened.

  package application;  import java.io.File;  import javafx.application.Application;  import javafx.scene.Scene;  import javafx.scene.control.*;  import javafx.scene.layout.StackPane;  import javafx.stage.FileChooser;  import javafx.stage.Stage;    public class MainClass extends Application {  public static void main(String[] args) {  launch(args);  }  @Override  public void start(Stage primaryStage)  {  Button btn = new Button(“SAVE”);  btn.setOnAction(e->  {  FileChooser file = new FileChooser();  file.setTitle(“Save Image”);  //System.out.println(pic.getId());  File file1 = file.showSaveDialog(primaryStage);  System.out.println(file1);  });    StackPane root = new StackPane();  Scene scene = new Scene(root,200,300);  primaryStage.setScene(scene);  root.getChildren().add(btn);  primaryStage.show();  }    }
