Java 2d array?

Question

Just a simple question guys, lets say I have a 2 dimensional array's called a. How do I create a new 2d array called result that has the same number of row's and column's as array a??

Answer 1

//Let the array be an integer array

int row=a.length , column=0 ;
int[] result=new int[row][] ;
for (int i=0 ; i column=a[i].length ;
result[i] = new int [ column ]
}
// Guess this should work fine........

Answer 2

int result[][] = new int[a.length][a[0].length];
