bubble sort

class Main {
  public static void main(String[] args) {
    int[] nums = {5, 8, 3, 2, 1, 22, 15};

    for (int i = 0; i < nums.length - 1; i++) {
      for (int j = 0; j < nums.length - i - 1; j++) {
        if (nums[j] > nums[j + 1]) {
          int temp = nums[j];
          nums[j] = nums[j + 1];
          nums[j + 1] = temp;
        }
      }
    }

    for (int i = 0; i < nums.length; i++) {
      System.out.println(nums[i]);
    }
  }
}

class Main {
  public static void main(String[] args) {
    int[] nums = {5, 8, 3, 2, 1, 22, 15};

    for (int i = 0; i < nums.length - 1; i++) {
      for (int j = 0; j < nums.length - i - 1; j++) {
        if (nums[j] > nums[j + 1]) {
          int temp = nums[j];
          nums[j] = nums[j + 1];
          nums[j + 1] = temp;
        }
      }
    }

    for (int i = 0; i < nums.length; i++) {
      System.out.println(nums[i]);
    }
  }
}

in this bubble sort why we need 2 loops? and we used

nums[j]

nums[j]

instead of

nums[i]

nums[i]
