Which of the following properly counts and return the number of positive numbers in the array given?

public static int countPositive(int[] nums) { int count = 0; for(int i = 0; i < nums.length; i++) { if(nums[i] > 0) { count++; } } return count; }

public static int countPositive(int[] nums) { int count = 0; for(int i = 0; i < nums.length; i++) { if(nums[i] > 0) { count++; } return count; } }

public static int countPositive(int[] nums) { int count = 0; for(int i = 0; i < nums.length - 1; i++) { if(nums[i] > 0) { count++; } } return count; }

public static int countPositive(int[] nums) { int count = 0; for(int i = 0; i < nums.length; i++) { if(i > 0) { count++; } } return count; }
