Hi Nitin,
You are right a two dimensional can be declared by <code> int[][]x=new int[2][]; // Legal</code>, but <CODE> int[][]x=new int[][2]; // is ILLEGAL </CODE>.
You may like to see the folowing code:

public class TestArray{
public static void main(String [] args) {
int twoDimArray[][]  = new int [2][];    // creates 2 rows 
for(int i= 0;i<twoDimArray.length;i++) {>
twoDimArray[i] = new int[i+1];             // constructs a growable i th column 
  }
 }
}

Hope this serves your purpose.
All the best for your SCJP.
Cheers,
