Please find the code below:::

CopyData.java

package graphichal;

import java.awt.Dimension;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JTextField;

public class CopyData{
   CopyData(){
       final JFrame f=new JFrame(); //we are using jframe
       f.setPreferredSize(new Dimension(800,300));
       f.setLayout(null);
       final JButton copy=new JButton("Copy");
       copy.setBounds(0, 50, 270,30);
       f.add(copy);
      
       final JButton clear=new JButton("Clear");
       clear.setBounds(400, 50, 270,30);
       f.add(clear);
      
       final JTextField field1=new JTextField("");
       field1.setBounds(0, 0, 270,30);
       f.add(field1);
      
       final JTextField field2=new JTextField("");
       field2.setBounds(400, 0, 270,30);
       f.add(field2);

       copy.addActionListener(new ActionListener() {
          
           @Override
           public void actionPerformed(ActionEvent arg0) {
               field2.setText(field1.getText());
           }
       });
      
       clear.addActionListener(new ActionListener() {
          
           @Override
           public void actionPerformed(ActionEvent arg0) {
               field2.setText("");
               field1.setText("");
           }
       });

       f.pack();
       f.setVisible(true);
   }

   public static void main(String[] args){
       CopyData f = new CopyData();

   }
}

output:
