What will be the output of the following program?

class RecursiveFor 
{
    public static void main(String[] args) 
    {
        int out = 15;
        for (int i = 4; i < 6; i++) 
        {
            for (int j = 7; j >= 5; j--) 
            {
                if (i == j) 
                //break;
                if (i > j) 
                {
                    out += main(i, j);
                } 
                else 
                {
                    out += main(j, i);
                }
            }
        }
        System.out.println("out = " + out);
    }

    private static int main(int a, int b) 
    {
        if (a - b == 0) 
        {
            return 2;
        }
        return a - main(a - 1, b);
    }
}

	out = 78
	out = 32
	out = 17
	Compilation Error
	Goes into infinite loop
