Question

In Java:

Squares iteratively rena Pevac Use constants SIZE = 500 and DIST = 20. Write application with methods • public void concentricsquares4colorFill(int x, int color Group g) • public void concentricsquares4colorfil Rec (int int color, Group Both methods draw the same concentric squares. First method does it iteratively, and the second one does it recursivlyYou must have your own 4 colors, and not the ones I used. In addition, you must put your first and last name in the title bar. First method will have "Squares iteratively + your names", second method will have "Squares recursively + your names in the title bar.

Answer 1

Working java code:-

ConcentricSquareGraphics.java 1 import java.awt.Canvas; 2 import java.awt.Color; 3 import java.awt.Graphics; 5 import javax.swing.JFrame; 7 public class ConcentricSquareGraphics extends Canvas{ 0 static int SIZE=500; int DIST=10; 10 11 12 14 public void paint(Graphics g) { 15 17 int sz=SIZE;//temp variable for size int dis=0;//temp variable for distance int i=0; setBackground(Color.WHITE); 18 19 20 while(sz-dis>=DIST) AWNA g.setColor(Color.GREEN); g.fillRect(i, i,sz-dis,sz-dis); 25 26 i+=DIST; dis=2*i; 27 28 g.setColor(Color.MAGENTA); g.fillRect(i, i, sz-dis, sz-dis); O N m nm m m m m m m m mm n N O i+=DIST; dis=2*i; g.setColor(Color.RED); g.fillRect(i, i, sz-dis, sz-dis); 39 10 i+=DIST; dis=2*i; 41 ων 44 45 g.setColor(Color.BLACK); g. fillRect(i, i, sz-dis, sz-dis); 46 47 48 i+=DIST; dis=2*i; 49 50 Page 1

ConcentricSquareGraphics.java 1 import java.awt.Canvas; 2 import java.awt.Color; 3 import java.awt.Graphics; 5 import javax.swing.JFrame; 7 public class ConcentricSquareGraphics extends Canvas{ 0 static int SIZE=500; int DIST=10; 10 11 12 14 public void paint(Graphics g) { 15 17 int sz=SIZE;//temp variable for size int dis=0;//temp variable for distance int i=0; setBackground(Color.WHITE); 18 19 20 while(sz-dis>=DIST) AWNA g.setColor(Color.GREEN); g.fillRect(i, i,sz-dis,sz-dis); 25 26 i+=DIST; dis=2*i; 27 28 g.setColor(Color.MAGENTA); g.fillRect(i, i, sz-dis, sz-dis); O N m nm m m m m m m m mm n N O i+=DIST; dis=2*i; g.setColor(Color.RED); g.fillRect(i, i, sz-dis, sz-dis); 39 10 i+=DIST; dis=2*i; 41 ων 44 45 g.setColor(Color.BLACK); g. fillRect(i, i, sz-dis, sz-dis); 46 47 48 i+=DIST; dis=2*i; 49 50 Page 1
OUTPUT:-

Squares iteratively Your Name - O X
