How do you find the largest and smallest number in an unsorted integer array?

Answer:

Here's a code snippet find largest and smallest number in an unsorted array.

       public class MaximumMinimumArrayDemo{
       public static void main(String args[]) {
       largestAndSmallest(new int[]{-20, 34, 21, -87, 92,Integer.MAX_VALUE});
       largestAndSmallest(new int[]{10, Integer.MIN_VALUE, -2});
       largestAndSmallest(new int[]{Integer.MAX_VALUE, 40,
       Integer.MAX_VALUE});
       largestAndSmallest(new int[]{1, -1, 0});
       }
        public static void largestAndSmallest(int[] numbers) {
        int largest = Integer.MIN_VALUE;
        int smallest = Integer.MAX_VALUE;
        for (int number : numbers) {
        if (number > largest) {
        largest = number;
       
        } else if (number < smallest) {
        smallest = number;
        }
        }
        System.out.println("Given integer array : " + Arrays.toString(numbers));
        System.out.println("Largest number in array is : " + largest);
        System.out.println("Smallest number in array is : " + smallest);
       }
       }
