Spawning an array of bullets

Now we know the basics of arrays we can get started spawning a load of bullets at the same time and store them in an array.

Tip

Make sure you deleted the temporary code from the Spawning a bullet section before proceeding.

Add a few control variables and declare an array of bullets as a member of BulletHellGame. Add this code just before the constructor.

// Up to 10000 bullets
private Bullet[] mBullets = new Bullet[10000];
private int mNumBullets = 0;
private int mSpawnRate = 1;

private Random mRandomX = new Random();
private Random mRandomY = new Random();

We have an array called mBullets, capable of holding 10000 bullets. The new keyword initializes the array, not the Bullets within the array. We also have two int variables ...
