Add '+' sign to integer subtraction operation result

I am performing subtraction operation in my code, and convert the received result to string. The result could be grater than 0 or negative. In case of negative result the '-' is automatically added to the result string.

I need to add the '+' sign, If i received possitive result. Please, advise me the most simple way to do that.

My code:

return String.valueOf(settlingScoreMap.get(market.getSettlingScore()).getAway()
          - settlingScoreMap.get(market.getSettlingScore()).getHome());

public static void main(String[] args) {
    int val1 = 5;
    int val2 = 4;

    int result = val1 - val2;

    System.out.println(result > 0 ? "+" + result : String.valueOf(result));
}

int x=5;
        int y=3;
        int result=x-y;
        if (result<=0) 
            System.out.println(String.valueOf(result));
        else
            System.out.println("+"+String.valueOf(result));

Use String.format:

String.format("%+d", theIntValueToPrint)
                ^ This indicates that the sign should be added.
