小弟初学java,最近在写一个拼图游戏的程序,在写得过程中考虑要随机排列图片,经过一番研究终于学出来了,我写得这个不是很好,在高手看来可能算不了什么,但是对于我这样初学的人我想还会有一些帮助的,所以就把它写出来了!!!
代码如下:
package PT;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.Icon;
import java.awt.GridLayout;
import javax.swing.ImageIcon;
class myPanel extends JPanel implements ActionListener
{
JButton bt1,bt2,bt3,bt4,bt5,bt6,bt7,bt8,bt9;
ImageIcon ico1=new ImageIcon("1.jpg");
ImageIcon ico2=new ImageIcon("2.jpg");
ImageIcon ico3=new ImageIcon("3.jpg");
ImageIcon ico4=new ImageIcon("4.jpg");
ImageIcon ico5=new ImageIcon("5.jpg");
ImageIcon ico6=new ImageIcon("6.jpg");
ImageIcon ico7=new ImageIcon("7.jpg");
ImageIcon ico8=new ImageIcon("8.jpg");
ImageIcon[] ico=new ImageIcon[8];
public myPanel()
{
int[] a=new int[8];
for(int i=0;i<a.length;i++)
{
a[i]=(int)(Math.random()*8+1);
for(int j=0;j<i;j++)
{
if(a[j]==a[i])
{
i--;
break;
}
}
}
for(int i=0;i<a.length;i++)
{
ico[i]=new ImageIcon(a[i]+".jpg");
// System.out.println (a[i]);
}
this.setLayout(new GridLayout(3,3));
