myrect.java

Java实现简单画图程序随机生成三种图形颜色等

import java.awt.Graphics;

public class MyRect extends MyShape
{
	private int wide,hight;
	
	public MyRect()
	{
		
	}
	
	public MyRect(int x1,int y1,int x2,int y2)
	{
		super(x1, y1, x2, y2);
		wide=Math.abs(x2-x1);
		hight=Math.abs(y2-y1);
	}
	
	public void draw(Graphics g)
	{
		g.drawRect(getX1(),getY1(),wide,hight);
	}
}
