Hi there I am trying to get this to calculate the winner from 4 players (The game is the classic card game war) but I can only get it to do two. the first bit of the code is my Card class and the second bit is the main program where there are more if statements for working out the winner. the issue i'm having is with the method "getWinner". I have included the deck class also if that is needed (at the bottom). package warcard;
public class Card
{
private int value, suit;
private String result, suitStr;
/**
* @param num represents value of card
* @param type represents the suit of card
*/
public Card(int num, int type)
{
/**
* Class constructor.
*/
value = num;
suit = type;
switch(value)
{
case 1: result = "Ace";
break;
case 2: result = "Two";
break;
case 3: result = "Three";
break;
case 4: result = "Four";
break;
case 5: result = "Five";
break;
case 6: result = "Six";
break;
case 7: result = "Seven";
break;
case 8: result = "Eight";
break;
case 9: result = "Nine";
break;
case 10: result = "Ten";
break;
case 11: result = "Jack";
break;
case 12: result = "Queen";
break;
case 13: result = "King";
break;
default: result = "";
break;
}
switch(suit)
{
case 1: suitStr = "Clubs";
break;
case 2: suitStr = "Diamonds";
break;
case 3: suitStr = "Hearts";
break;
case 4: suitStr = "Spades";
break;
}
}
/**

*/
public int getNum()
{
return value;
}
public int getSuit()
{
return suit;
}
/**

public void setVal(int choice)
{
value = choice;
}
public void setSuit(int choice)
{
suit = choice;

public String getWinner(Card play)
{
String flag = "";
if(value == play.getNum())

flag = "win";

flag = "tie";
else

}

else
