Store a 2D array within another array -- Java

Question

I need to be able to store a 2D boolean array within another array, which is as follows...

   boolean[][] Player = new boolean[1][2];       

   Object[] Game = new Object[1];

   Player[0][0] = true;
   Player[0][1] = false;

   Game[0] = Player[0][0];

I need to be able to set each Game[] index with a Player, but what I have above doesn't work. Is there any way to insert an array within an array?

Please rename your variable, it's very confusing. Until now I still think Player is a class.. I just can't get it out of my mind :) — Maroun

If you want to store the 2D array in Game[0] then you should do

Game[0] = Player;

Other points:

I would suggest you create a Player class:
```
class Player {
    boolean flag1;
    boolean flag2;
}
```
instead of creating arrays of booleans.

Your player array (Game) would then have the type Player[].
Let variable names start with lower case and class names start with capital case.
If you really want to use arrays, I'd suggest you change the type of Game to boolean[][][].

You are trying to set into Game[0] field boolean value. Do this

Game[0] = Player;

if you want to store array into another array. And my advice to U: if U want to become a good java programmer write good code using JCC. Name of non final variable begins with lowercase letter so instead of Game and Player, in java so call classes, use game and player.

If you want to store each player in game array index you should write:

Game[0] = Player;
