Find largest and smallest value in array ?

>> In Java, we can find smallest and largest value in given array by using for loop, collections, arrays sort,...

import java.util.Arrays;
import java.util.Collections;
import java.util.List;

public class largeSmallArray {
    public static void main(String[] args) {
    int numbers[] = { 2, 4, -3, -4, 0, 10, 5, 20 };

    int smallest = numbers[0];
    int largest = numbers[0];

    for (int i = 1; i < numbers.length; i++) {
        if (numbers[i] > largest) {
            largest = numbers[i];
        }
        if (numbers[i] < smallest) {
            smallest = numbers[i];
        }
    }
    System.out.println("largest value in array using for loop=" + largest);
    System.out.println("smallest value in array using for loop=" + smallest);
    
    System.out.println("<<---------------------------------------->>");
    Arrays.sort(numbers);
    System.out.println("Smallest value using arrays sort=" + numbers[0]);
    System.out.println("Largest value using arrays sort=" + numbers[numbers.length - 1]);
    
    System.out.println("<<---------------------------------------->>");
    Integer b[] = { 1, 2, 5, 6, 3, 2, -1, -2 };
    
    List<Integer> list = Arrays.asList(b);
    Collections.sort(list);
    System.out.println("Smallest value using collections=" + list.get(0));
    System.out.println("Largest value using collections=" + list.get(list.size() - 1));
  }
}
