I am new to programming but I tried to make my code as readable as possible! Hopefully you can see what it does before you run the program. I did not implement a ups or fps controller, the animation may be fast for some computers and slower for others. I also tried to use the information provided to me from my first code review. Eventually I will be making this concept into a dodge the meteors type game.

import javax.swing.*;
import java.awt.*;

//changing these values will change the size of the game, while still remaining functional
//within the size limit specified.
public static final int WINDOW_WIDTH = 600;
public static final int WINDOW_HEIGHT = 400;
//Creates a Square object Array
Square[] squareArray = new Square[20];
public Game() {
//initializes square objects
for (int i = 0; i < squareArray.length; i++)
squareArray[i] = new Square();
}
public void paint(Graphics graphics) {
//makes background black
graphics.setColor(Color.black);
graphics.fillRect(0, 0, WINDOW_WIDTH, WINDOW_HEIGHT);
//paints square objects to the screen
for (Square aSquareArray : squareArray) {
aSquareArray.paint(graphics);
}

//calls the Square class update method on the square objects
