writer.java

用ＪＡＶＡ 编写的一个菜单程序 实现了一些基本计算和信息的录入

import java.awt.*;
import javax.swing.*;
public class Writer{
	public static void main(String args[]){
		JFrame frame=new JFrame("Writer");
		Container c=frame.getContentPane();
		c.setLayout(null);
	   String str1[]={"tt","yy","uu","rr"};
	   JList cp1=new JList(str1);
	   cp1.setSize(400,400);
	   cp1.setLocation(0,0);
	   c.add(cp1);
	   
	   String str2[]={"aa","bb","cc","dd"};
	   JList cp2=new JList(str2);
	   cp2.setSize(400,400);
	   cp2.setLocation(400,0);
	   c.add(cp2);
	   
	   
	   
	   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	   frame.setSize(800,400);
	   frame.setVisible(true);
	
	
	
	
	
	
	
	
	
	
	
	}
