Java > Array-1 > double23 (CodingBat Solution)

Problem:

Given an int array, return true if the array contains 2 twice, or 3 twice. The array will be length 0, 1, or 2.

double23({2, 2}) → true
double23({3, 3}) → true
double23({2, 3}) → false

Solution:

public boolean double23(int[] nums) {
  if (nums.length < 2)
    return false;
  if ((nums[0] == 2 && nums[1] == 2) || (nums[0] == 3 && nums[1] == 3))
    return true;
  else
    return false;
}
