调试过了，下面的代码可以实现。
import java.awt.*;
import java.awt.event.*;
public class applicationgraphicsinout
{
public static void main(String args[])
{
new FrameInOut();
}
}

class FrameInOut extends Frame implements ActionListener
{
Label prompt;
TextField input,output;

public FrameInOut()
{
prompt=new Label("input your name:");
input=new TextField(20);
output=new TextField(20);
add(prompt);
add(input);
add(output);
input.addActionListener(this);
setSize(300,200);
show();
}
public void actionPerformed(ActionEvent e)
{
output.setText(input.getText()+"welcome!");
}
}
