Java > Warmup-1 > sumDouble (CodingBat Solution)

Problem:

Given two int values, return their sum. Unless the two values are the same, then return double their sum.

sumDouble(1, 2) → 3
sumDouble(3, 2) → 5
sumDouble(2, 2) → 8

Solution:

public int sumDouble(int a, int b) {
  if (a == b)
    return 2 * (a + b);
  else
    return a + b;
}
