Question

Write a Java program that reads 5 integers, each of which is in the range of 1 and 13 representing a simplified poker card with no suit. Your program should then print the ranking of the hand with card number(s) besides the ranking. The rankings to determine are Four of a Kind(4 of the 5 cards of the same rank), Full House(3 of the 5 cards of the same rank, and 2 cards of another rank), Straight(5 cards of sequential rank), Three of a Kind(only 3 cards of the same rank), Two Pair(2 cards of the same rank, 2 cards of another rank, and no card of either rank), One Pair(only 2 of 5 cards are of the same rank), and High Card(no two cards of the same rank). Some sample runs are:

input: 2, 3, 2, 2, 2;      output: Four of a Kind(2)

input: 2, 3, 2, 3, 2;      output: Full House(2, 3)

input: 2, 3, 4, 5, 1;      output: Straight(5)

input: 1, 13, 11, 10, 12; output: Straight(1)

input: 2, 3, 2, 2, 4;      output: Three of a Kind(2)

input: 1, 9, 8, 9, 1;      output: Two Pair(1, 9)

input: 2, 9, 8, 9, 2;      output: Two Pair(9, 2)

input: 3, 9, 8, 9, 1;      output: One Pair(9)

input: 2, 10, 7, 12, 5;    output: High Card(12)

input: 2, 1, 7, 12, 5;     output: High Card(1)

hint: sort the cards before checking.
