Java > Array-2 > more14 (CodingBat Solution)

Problem:

Given an array of ints, return true if the number of 1's is greater than the number of 4's

more14({1, 4, 1}) → true
more14({1, 4, 1, 4}) → false
more14({1, 1}) → true


Solution:

public boolean more14(int[] nums) {
  int count1 = 0;
  int count4 = 0;
  boolean isTrue = false;
  
  for (int i = 0; i < nums.length; i++) {
    if (nums[i] == 1)
      count1++;
    if (nums[i] == 4)
      count4++;
  }
  
  if (count1 > count4)
    isTrue = true;
  
  return isTrue;
    
}

    Not sure why the formatting screwed up on previous comment...

    With Java Stream

    public static boolean more14(int[] nums) {

    long count1 = Arrays.stream(nums)
    .filter(i -> i == 1)
    .count();

    long count4 = Arrays.stream(nums)
    .filter(i -> i == 4)
    .count();

    return count1 > count4;
    }
