Implementing a card game in JAVA - Help with deck

I have jsut simplified the construtor to jsut print the value of masterPack[0].

I get an exception, the problem is masterPack is not accepted in the Construtor.. i dont know why?

public Dec(int val)

{

allocateMasterPack();

System.out.println("Printing the values in constructor");

cards = new Card[52];

for (int k = 0; k < cards.length; k++)

cards[k]= new Card();

System.out.println ( masterPack[0]);

// init(val);

}

Output:

======

allocateMasterPack() activated
