and I want to us the same number but randomly rearrange it like this:

Is there a way I can do this easily in java?

This will this help you : Random Numbers – shuffling.

Not a complete code, just a snippet from the link

Random rgen = new Random();  // Random number generator
int[] cards = new int[52];  

//--- Initialize the array to the ints 0-51
for (int i=0; i<cards.length; i++) {
    cards[i] = i;
}

//--- Shuffle by exchanging each element randomly
for (int i=0; i<cards.length; i++) {
    int randomPosition = rgen.nextInt(cards.length);
    int temp = cards[i];
    cards[i] = cards[randomPosition];
    cards[randomPosition] = temp;
}
