java 自己写的小程序！！！欢迎使用！！！！

import java.awt.*;

public class powerup{
	private int xPos;
	private int yPos;
	private int function;
	private Rectangle Powerup;
	private int display = 0;
	private int displaytime;

	public powerup(){
		xPos = 24 + (int)(Math.random()*475);
		yPos = 24 + (int)(Math.random()*475);
		int a = (int)(Math.random()*20);
		if(0 <= a && a< 3)
			function = 1;
		if(3 <= a && a < 6)
			function = 2;

			function = 3;

			function = 6;
		if(16 <= a && a < 20)
			function = 7;
