connecting jframe

[nachinne_manche]

Actually I am new to java so I want to know how we link these to files. After pressing Next Button it should change to Welcome Frame.

Enter.java

 import java.awt.FlowLayout;
 
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;
 
public class Enter extends JFrame {
 
    public Enter() {
        // TODO Auto-generated constructor stub
 
        setLayout(new FlowLayout(FlowLayout.LEFT, 10, 20));
 
        add(new JLabel("Name"));
        add(new JTextField(8));
        add(new JLabel("Address"));
        add(new JTextField(15));
        add(new JLabel("Surname"));
        add(new JTextField(8));
        add(new JLabel("Phone"));
        add(new JTextField(8));
        add(new JButton("Next"));
    }
 
 
    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
    	Enter myProg = new Enter();
        myProg.setTitle("Ceng 344 - Lab 7");
        myProg.setSize(450, 400);
        myProg.setLocationRelativeTo(null);
        myProg.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        myProg.setVisible(true);
    }
 
}

Welcome.java

 import java.awt.FlowLayout;
 
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;
 
public class welcome extends JFrame {
 
    public welcome() {
        // TODO Auto-generated constructor stub
 
        setLayout(new FlowLayout(FlowLayout.LEFT, 10, 20));
 
        add(new JLabel("Welcome"));
        }
 
 
    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        welcome myProg = new welcome();
        myProg.setTitle("Ceng 344 - Lab 7");
        myProg.setSize(450, 400);
        myProg.setLocationRelativeTo(null);
        myProg.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        myProg.setVisible(true);
    }
 
}

After pressing Next Button it should change to Welcome Frame.

Look at using an ActionListener with the button. See the tutorial:
How to Write an Action Listener (The Java™ Tutorials > Creating a GUI With JFC/Swing > Writing Event Listeners)
