//需要stdraw class 支持 import java.awt.Color; public class points { 
    public points(){ 
    
    } 
   public void drawIt(){ 
                StdDraw.setXscale(0,20); 
                StdDraw.setYscale(0,20); 
                StdDraw.line(20,0,0,0); 
                StdDraw.line(0,20,0,0); 
                   for(double d =0; d<=20; d++){ 
                      for(double a =0; a<=20; a++){ 
                           double z = (double) (Math.random()*20)+0; 
                           double x = (double) (Math.random()*20)+0; 
                            d=z;a=x; 
                            Color c = new Color(255,0,0); 
                            StdDraw.setPenColor©; 
                            StdDraw.show(); 
                            StdDraw.point(z,x); 
                    } 
            } 
 } 
public static void main(String[] args) { 
       
      points point = new points(); 
       point.drawIt(); 
    } 
}
