之三：程序主界面
等级选择“初级”，进入“程序主界面”，效果见下图：
准备工作：
Images文件夹下，放置level.png图片一张。
代码实现：
PCBoard .java
package com.fivechess.view;
public class PCBoard extends Board {
private PCChessBoard2 pcchessboard2;//棋盘
public PCBoard() {
init();
}
public void init() {
pcchessboard2=new PCChessBoard2();
pcchessboard2.setBounds(200, 50, 600, 700);
pcchessboard2.setVisible(true);
add(pcchessboard2);
}}
//Board类的代码：
package com.fivechess.view;
import java.awt.Graphics;
import javax.swing.JFrame;
public class Board extends JFrame {
public Board() {
setLayout(null); //取消原来布局
setBounds(300,50,800,700);
//init1();
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setResizable(false);
setTitle("雷雷的五子棋");
}
/**
* 绘图
* @param g
*/
public void paint(Graphics g)
{
super.paint(g);
repaint();
}}
