youYou can create them just the way others have mentioned. oneOne more point to add, you: You can even create a skewed 2 dimensionaltwo-dimensional array with each row, not necessarily having the same number of collumns, like this:
int array[][]=newarray[][] = new int[3][];
array[0]=newarray[0] = new int[3];
array[1]=newarray[1] = new int[2];
array[2]=newarray[2] = new int[5];
