In this problem, you will create methods that take an int array, convert it to an ArrayList, and return the maximum or minimum value using Collections.max() and Collections.min().

Learning Objective: Understand how to find maximum and minimum values in a list using Collections.max() and Collections.min()

Overview

Collections.max() and Collections.min() are utility methods that return the maximum and minimum elements in a collection.

Specifications

• Create a findMax(int[] numbers) method
  • Convert the int array to an ArrayList and return the max value using Collections.max()
• Create a findMin(int[] numbers) method
  • Convert the int array to an ArrayList and return the min value using Collections.min()

Method Signatures

public static int findMax(int[] numbers)
public static int findMin(int[] numbers)

Examples

findMax([34, 12, 56, 7, 89, 23]) → 89
findMin([34, 12, 56, 7, 89, 23]) → 7
