New to Java

i am trying to create a array full of random numbers which i have done with:

public void randArray(int[][]rand){
      for (row=0; row<rand.length; row++)
  {
   for (col=0; col<rand[row].length; col++)
   {
     t = (int)(Math.random()*6);
     rand[row][col] = t;
   }
      }
   }

but i need it so that it has 2 of each random number not just 1
eg if i printed out the array and took the each number they wud be in multiples of 2

rand = 2 4 5 0
1 2 0 3
3 2 5 1
0 0 4 2

reading that back myself i dont think it makes any sense at all but i cant think of any other way to describe it
