Java - Array Shuffle from Array1 to Array 2

Im using Eclipes Android. So here's my array1, and I want it to transfer to another array(array2) randomly. I've been working on it for hours but I can't get it right.

int array1[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
                11,12,13,14,15,16,17,18,19,20,
                21,22,23,24,25,26,27,28,29,30,
                31,32,33,34,35,36,37,38,39,40,
                41,42,43,44,45,46,47,48,49,50};

I want to transfer it to my new array, array2 randomly.

I'm still new to java and still learning.Thanks.
