For this assignment you will make a simple animation of fireworks. This common animation is called a “starfield” since it can also be used to simulate movement through a field of stars. You will use a class to represent each “particle”.

Program requirements:
1. Your program must use a class that represents "particles". Your class should have at least 5 data members: X and Y positions, Color, Direction and Speed. (Hint use doubles for X, Y, Speed and Angle)
2. All the particles must be stored in an array.
3. Your program must use at least one constant (for number of particles).
4. Your class must have a constructor that uses the Random class to initialize the data members

Steps to completing this assignment

1. Start with the same "fill in the blank" thread applet that you used in assignment 4
2. Write a Particle class. You will need the following members:
   • 5 data members: X and Y positions, Color, Angle and Speed. (Hint use doubles for X, Y, Speed and Angle)
   • Your class will need an instance of the Random class. It should be static.
   • Color randomColor(), randomly chooses one of the 13 basic colors and returns it.
   • Particle(), the class constructor
   • void move(), Takes the cos of the angle times the speed and adds it to the X coordinate. Does the same to Y with the sin of the angle.
   • void draw(Graphics g), sets the current color to the color of the particle and draws a dot using fillOval()
3. Now add one Particle to the applet, much like you did with the Ball in assignment 4.
4. Now modify the applet so you have an array of Particles.

Random class

import java.util.Random;

public class RandomDemo extends Applet
{
	public void paint(Graphics g)
	{
	   Random numberGen = new Random();

	   //display a random true or false
	   System.out.println(numberGen.nextBoolean());

	   //0 <= random decimal < 1
	   System.out.println(numberGen.nextDouble());

	   //approx -5 < "Gaussian" decimal < approx 5
	   System.out.println(numberGen.nextGaussian());

	   //Integer.MIN_VALUE < Random Integer < Integer.MAX_VALUE
	   System.out.println(numberGen.nextInt());

	   //0 <= Random Integer < 5
	   System.out.println(numberGen.nextInt(5));
	}
}
