Question

I'm having trouble to compile and run this Java code in visual studio code as there's only an error in the main function.

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) < hand[h][i].charAt(0))

{temp = hand[h][j];

hand[h][j] = hand[h][i];

hand[h][i] = temp;

}

else

if (hand[h][j].charAt(0) == hand[h][i].charAt(0))

{ if (Order.get(hand[h][j].charAt(1)) < Order.get(hand[h][i].charAt(1)))

{temp = hand[h][j];

hand[h][j] = hand[h][i];

hand[h][i] = temp;

}

} //for j

} // for i

}// for h

}

public static void printHand()

{ for (int h=0;h<3;h++) {

for (int i=0;i<5;i++)

{ System.out.println(hand[h][i]);}

System.out.println();

}

public static void getPoints( )

{ int total=0;

for (int h=0;h<3;h++)

{

for (int i=0;i<5;i++)

{ String myStr = Character.toString(hand[h][i].charAt(1));

total += Code.get(myStr);

}

scores[h]=total;

System.out.println(scores[h]);

total=0;

}

public static int getmax()

{ int max=0;

int handNum=0;

for (int h=0;h<3;h++)

{ if (scores[h]>max)

{max=scores[h];

handNum=h;

}

System.out.println("Maximum points :" + max);

return handNum+1;

}

public static void main(String[] args) throws IOException {

Code.put("A",1);

Code.put("2",2);

Code.put("3",3);

Code.put("4",4);

Code.put("5",5);

Code.put("6",6);

Code.put("7",7);

Code.put("8",8);

Code.put("9",9);

Code.put("X",10);

Code.put("J",10);

Code.put("K",10);

Code.put("Q",10);

Order.put('A',1);

Order.put('2',2);

Order.put('3',3);

Order.put('4',4);

Order.put('5',5);

Order.put('6',6);

Order.put('7',7);

Order.put('8',8);

Order.put('9',9);

Order.put('X',10);

Order.put('K',11);

Order.put('Q',12);

Order.put('J',13);

sortHand();

printHand();

getPoints();

int maxh=getmax();

System.out.println("Maximum points are for hand " + maxh);

}
