Functions and Arrays

Loops, Advanced Color Functions - Con't

Here we use two nested loops to draw an array of graphical elements. The outer loop is for the horizontal row, the inner loop for the vertical. The fill3DRect and draw3DRect functions enable you to easily draw rectangles with a raised or lowered impression, depending on the last boolean parameter.

//Sourcecode

import java.awt.*; import java.applet.*; public class Project14 extends Applet { public void paint (Graphics g) { //draw tiles with circles inside //we use two nested loops to do this: for(int x=0;x<300;x+=30) for(int y=0;y<300;y+=30) { g.setColor(Color.lightGray); g.fill3DRect(x,y,30,30,true); g.setColor(Color.red); g.drawOval(x+2,y+2,25,25); g.setColor(Color.lightGray); g.draw3DRect(x+7,y+7,15,15,false); } } }
