java 扫雷游戏源码案例项目

代码如下

import java.awt.*;import javax.swing.*;//图形计数器JCounter三位class JCounter extends JPanel {        private static final long serialVersionUID = 1L;        private ImageIcon [] numSet = { new ImageIcon("image/c0.gif"), new ImageIcon("image/c1.gif"),                                             new ImageIcon("image/c2.gif"), new ImageIcon("image/c3.gif"),                                             new ImageIcon("image/c4.gif"), new ImageIcon("image/c5.gif"),                                             new ImageIcon("image/c6.gif"), new ImageIcon("image/c7.gif"),                                             new ImageIcon("image/c8.gif"), new ImageIcon("image/c9.gif"),

                        counter[i].setSize(13,23);
                        counter[i].setMargin(space);
                        add(counter[i]);
                }

                resetImage();         
        }        
        public int getCounterNum() {        
                return(counterNum);
        }        
        private void setCounterNum(int num){                this.counterNum = num;
        }        
        private void resetImage() {                int ones, tens, hundreds;
                ones = counterNum % 10 ;
                tens = counterNum % 100/10;
                hundreds = (counterNum) % 1000/100;                this.counter[0].setIcon(numSet[hundreds]);                this.counter[1].setIcon(numSet[tens]);                this.counter[2].setIcon(numSet[ones]);
        }
