I have used selectAll () and select (), but no use.
As we know if use keyboard SHIFT+END will select all the data in text field.

My code is below
textField.addFocusListener(new FocusAdapter (){
     public void focusGained (FocusEvent fe){
          textField.selectAll () ;
}) ;

Your code does work as expected.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class TfFocus{
  public static void main(String[] args){
    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    final JTextField tf = new JTextField("Get Focus Get Selected");
    frame.getContentPane().add(tf, BorderLayout.SOUTH);
    JTextArea ta = new JTextArea();
    frame.getContentPane().add(ta, BorderLayout.CENTER);
    tf.addFocusListener(new FocusAdapter(){
      public void focusGained (FocusEvent fe){
        tf.selectAll () ;
    frame.setBounds(0, 0, 400, 400);
    frame.setVisible(true);
    ta.requestFocus();
