write a program that takes an array and draws rectangles in java.

Answer 1

import java.awt.Graphics;

import javax.swing.JFrame;

import javax.swing.JPanel;

public class RectangleDrawer extends JPanel {

int[] rectangles;

public RectangleDrawer(int[] rectangles) {

this.rectangles = rectangles;

}

@Override

public void paintComponent(Graphics g) {

super.paintComponent(g);

for (int i = 0; i < rectangles.length; i += 4) {

int x = rectangles[i];

int y = rectangles[i + 1];

int width = rectangles[i + 2];

int height = rectangles[i + 3];

g.drawRect(x, y, width, height);

}

}

public static void main(String[] args) {

int[] rectangles = {10, 10, 50, 50, 70, 70, 150, 150};

JFrame frame = new JFrame();

frame.add(new RectangleDrawer(rectangles));

frame.setSize(400, 400);

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setVisible(true);

}

}
