I have a query. I have the following java code and I want the button to greet me to capture the name that the user types and when I click on the button, I will show it to me in the Jframe.

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;

public class Ventanita extends JFrame implements ActionListener {

public Ventanita() {
    jPanel.add(label);
    jPanel.add(jTextField);
    jPanel.add(jButton);
    jPanel.add(label1);
    jPanel.add(label2);
    add(jPanel);

}

public static void main(String[] args) {

    JFrame x = new Ventanita();
    x.setSize(400, 400);
    x.setVisible(true);        
    x.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}

JLabel label = new JLabel("Nombre");
JTextField jTextField = new JTextField("10");
JButton jButton = new JButton("Saluda");

JLabel label1 = new JLabel("Hola");
JLabel label2 = new JLabel(" ");
JPanel jPanel = new JPanel();

@Override
public void actionPerformed(ActionEvent ae) {

}

}

Based on the example you gave, and you edit the positions of the objects, I recommend that you review.

package pruebasdemetodos;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;

public class Ventanita extends JFrame implements ActionListener {

    JLabel label = new JLabel("Nombre");
    JTextField jTextField = new JTextField("10");
    JButton jButton = new JButton("Saluda");

    JLabel label1 = new JLabel("Hola");
    JLabel label2 = new JLabel("Cambio");
    JPanel jPanel = new JPanel();
public Ventanita() {
    jButton.addActionListener(this);
    jPanel.add(label);
    jPanel.add(jTextField);
    jPanel.add(jButton);
    jPanel.add(label1);
    jPanel.add(label2);
    add(jPanel);

}

public static void main(String[] args) {

    JFrame x = new Ventanita();
    x.setSize(400, 400);
    x.setVisible(true);        
    x.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}



@Override
public void actionPerformed(ActionEvent ae) {
    label2.setVisible(true);
    label2.setText(jTextField.getText());
}


}
