leverage.java

一些JAVA的小程序

import java.awt.*;

public class leverage{

   public leverage(int xPosition,int yPosition,boolean isDown){

       x=xPosition;
       y=yPosition;
       Down=isDown;
   }

   public void draw(Graphics g){
       if (Down){
           g.setColor(Color.red);
           g.drawRect(x,y,30,3);
           g.fillRect(x,y,30,3);
       }
       else{
           g.setColor(Color.red);
           g.drawRect(x-30,y,30,3);
           g.fillRect(x-30,y,30,3);
       }
   }

   //set the value for Down
   public void setDown(boolean flag){
       Down=flag;
   }

   //get the value of Down
   public boolean getDown(){
       return Down;
   }

   int x;
   int y;
   boolean Down;
}
