can you fix my java project? (i dont know how to set the different height for the second row and third row)

Rainbow.java

import java.awt.Color; import java.awt.Graphics; import java.awt.Graphics2D; import javax.swing.JComponent; import java.awt.Rectangle;

public class Rainbow { private int x; private int y; public Rainbow(int x1, int y1){ x=x1; y=y1; } public Rainbow(){ x=0; y=0; } public void draw(Graphics2D g2){ Rectangle qBox = new Rectangle(x,y,100,20); g2.setColor(Color.RED); g2.fill(qBox); Rectangle wBox = new Rectangle(x,y+20,100,20); g2.setColor(Color.ORANGE); g2.fill(wBox); Rectangle eBox = new Rectangle(x,y+40,100,20); g2.setColor(Color.YELLOW); g2.fill(eBox); Rectangle rBox = new Rectangle(x,y+60,100,20); g2.setColor(Color.GREEN); g2.fill(rBox); Rectangle tBox = new Rectangle(x,y+80,100,20); g2.setColor(Color.BLUE); g2.fill(tBox); Rectangle uBox = new Rectangle(x,y+100,100,20); Color indigo = new Color(75,0,130); g2.setColor(indigo); g2.fill(uBox); Rectangle iBox = new Rectangle(x,y+120,100,20); Color violet = new Color(143,0,255); g2.setColor(violet); g2.fill(iBox); } }

RainbowComponent.java

import java.awt.Graphics; import java.awt.Graphics2D;

import javax.swing.JComponent;

public class RainbowComponent extends JComponent {

private static final long serialVersionUID = 1L; public void paintComponent(Graphics g) { // Recover Graphics2D Graphics2D g2 = (Graphics2D) g; Rainbow flight1 = new Rainbow(0,0); flight1.draw(g2); Rainbow flight2 = new Rainbow(100,180); flight2.draw(g2); Rainbow flight3 = new Rainbow(0,200); flight3.draw(g2); }

}

Upper left-hand corner at 0,0. Height of 20

Upper left-hand corner at 100, 180. Height of 10
