Java使用图形用户界面万年历

1、9、万年历要求：使用图形用户界面。实现日期与星期的查询import java.awt.*;import java.awt.event.*;import java.text.*;import java.util.*;import javax.swing.*;import javax.swing.table.*; public class testl extends JFrame implements ActionListener private Calendar cal = Calendar. getInstance ();private String 口 str = "星期一&quo
