Question

JAVA JAVA

1- Create two arrays one for the rank of the playing cards and one for the suit.

2- Create an array of 52 strings that contain a deck of playing cards. The first 13 items are the cards, whose suit is clubs, the next 13 diamonds, the next 13 hearts and finally the spades. In this step, the array and the order of the cards should be printed.

3- Use the shuffling algorithm you have learnt in the lecture and shuffle the cards and print the result.

Answer 1
