In section $13\mathrm{.}2,$ these following $3$ methods are not finished. Your task is to finish these $3$ methods. Remember that you need to write a main method to test that these $3$ methods are working correctly.

One way to do that is to print out a deck of $52$ cards from the first card to the last

Then shuffle the deck of $52$ cards

Then print out the $52$ cards again. The second printout needs to be different from the first printout.

public void shuffle$()\{$

for each index i $\{$

$//$ choose a random number between i and length $-1$

$//$ swap the ith card and the randomly$-$chosen card

$\}$

$\}$

private static int randomInt$($int low, int high$)\{$

$//$ return a random number between low and high,

$//$ including both

$\}$

private void swapCards$($int i$,$ int j$)\{$

$//$ swap the ith and the jth cards in the array

$\}$
