Naming and initializing objects in an array

Now, Im currently wrinting a simple graphics program. In it I hava a Array called m_ball.

Now, m_ball is suposed to contain up to 20 instances of the class Ball.

Rigth now I do this by the following code =

        Ball m_activeBall0 = new Ball();
        Ball m_activeBall1 = new Ball();
        Ball m_activeBall2 = new Ball();
        m_ball[1] = m_activeBall0;
        m_ball[2] = m_activeBall1;
        m_ball[3] = m_activeBall2;

Now thats all sound and well. But aint it posible to do it in a for loop. some thing like this =

        for(int i = 0; i <m_ball.length;i++) {
            Ball m_activeBall[i] = new Ball();
            m_ball[i] = m_activeBall[i];

or have I lost it?

I simply cant seem to find a way to do this.

I tried Google, but cant seem to find the answer.

Oh.. yea. forgot to add. its Java.


Ball[] m_ball = new Ball[20];

for(int i = 0; i < m_ball.Length; i++)
   m_ball[i] = new Ball();

I wrote this in C# but I'm pretty much sure it's same with Java. Cheers. :)

You can use a for loop,:

for (int i = 0; i < m_ball.length; i++)
     m_activeBall[i] = new Ball();
     m_ball[i]       = m_activeBall[i];

Just to mention Arrays.copyOf(). If m_activeBall was created somewhere else you could make a copy of it:

Ball[] copy = Arrays.copyOf(m_activeBall, m_activeBall.length);
