Hi Friend,

Try this:

1)PassData.java:

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

class PassData extends JFrame
{
    JTextField text;
    PassData(){
        JLabel l=new JLabel("Name: ");
        text=new JTextField(20);
        JButton b=new JButton("Send");
        setLayout(null);
        l.setBounds(10,10,100,20);
        text.setBounds(120,10,150,20);
        b.setBounds(120,40,80,20);
        add(l);
        add(text);
        add(b);
        setVisible(true);
        setSize(300,100);
          b.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent e){
            String value=text.getText();
            NextPage page=new NextPage(value);
            page.setVisible(true);
            }
        });
    }
        public static void main(String[] args) 
    {
        new PassData();
    }
}

2)NextPage.java:

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

class NextPage extends JFrame
{
  NextPage(String st)
   {
     setLayout(null);
     setDefaultCloseOperation(javax.swing. WindowConstants.DISPOSE_ON_CLOSE);
     setTitle("Welcome");
     JLabel lab=new JLabel("Welcome  "+st);
     lab.setBounds(10,10,500,20);
     add(lab);
     setSize(300, 100);
      }
 }

Thanks
