Java > Logic-1 > love6 (CodingBat Solution)

Problem:

The number 6 is a truly great number. Given two int values, a and b, return true if either one is 6. Or if their sum or difference is 6. Note: the function Math.abs(num) computes the absolute value of a number.

love6(6, 4) → true
love6(4, 5) → false
love6(1, 5) → true


Solution:

public boolean love6(int a, int b) {
  if (a == 6 || b == 6)
    return true;
    
  int sum = a+b;
  int diff = Math.abs(a-b);
  
  if (sum == 6 || diff == 6)
    return true;
  else
    return false;
}

    return ((a == 6 || b == 6 ) || (a+b == 6) || Math.abs(a-b) == 6);

    public static boolean love6(int a, int b) {
    return ((a + b) == 6 || Math.abs(a - b) == 6);
    return (a == 6 || b == 6);
    }

    // Or

    public static boolean love6(int a, int b) {
    return (a + b) == 6;
    return (a == 6 || b == 6);
    return Math.abs(a - b) == 6;
    }

    these two blocks of code are not allowed. why?
