Using Java Library ArrayList as a List implementation, create a normal 52-card deck

Using Java Library ArrayList as a List implementation, create a normal 52-card deck Using Java Library ArrayList as a List implementation, create a normal 52-card deck with “Spades”, “Hearts “Diamonds’, ‘Clubs” as suit names and “Ace”, “2”, “3”,“4”5″, “6”, “7”, “8”, “9”, “10”, “Jack, “Queen”, “King” as rank names.

Write a program that takes as input : -

(1) the number of hands to deal and 

(2) the number of cards in each hand and generates required hands with pseudo-random output, using Java Library Random with seed as 0, to shuffle the cards.

Input format :-

Enter number of hands on first line

Enter number of cards per hand on next line

Output format :-

One hand is printed on each line
