I'm developing a card game that requires one deck of 52 cards using Java. The 52 card has 4 suits from top to bottom: diamonds (d), clubs (c), hearts (h), and spades (s). Each card has a point. The rest of the instructions are in the images. Based on the code below, it outputs the maximum points of all 5 sorted cards. Instead, I need the total point chosen from the suit that gives the highest point. The images shown are for reference purposes. import java.util.HashMap; import java.io.*; public class CardPointsList { static HashMap<String,Integer> Code = new HashMap<>(); static HashMap<Character,Integer> Order = new HashMap<>(); static String[][] hand= {{ "c5","s6","sK","dK","dA"},{"s7","s4","dJ","sA","h5"},{"sQ","d3","c9","hK","d5"}}; static int[] scores={0,0,0}; public static void sortHand() { String temp; for (int h=0;h<3;h++) {for (int i=0;i<5;i++) { for (int j=i+1;j<5;j++) { if (hand[h][j].charAt(0)…
