Thread: Array of a Class Type containing an array -- array sizes not know at compile time.

I have the following types declared.

class Piece
   {
   public byte type;
   public byte loc;
   }
 
class Config
   {
   public Config( int n ) { piece = new Piece[ n ]; }
   private Piece [] piece;
   private int next;
   private int parent;
   }
 
class QHT
   {
   private Config [] conf;
   public QHT( int m, int n );
   }

In the constructor for QHT, I want to allocate "conf" to an array of m "Config"s where each Config contains an array of n "Piece"s. The values of m and n are not known at compile time. (If necessary, I could fix the value of m at compile time but
I can't do this for n. Also, m will be rather large.)

How can I do this in Java?

Two steps in the constructor for QHT:

1. Set conf equal to a new array of m Configs.
   
   
2. Make a loop that sets each element of conf equal to a new Config(n).
