Here is a code that accepts five numbers and find the largest and smallest number from the array of input numbers.

import java.util.*;

public class FindLargestSmallestNumber {

        public static void main(String[] args) {
        Scanner input=new Scanner(System.in);
        System.out.println("Enter 5 numbers: ");
        int numbers[] = new int[5];
        for(int i=0;i<numbers.length;i++){
            numbers[i]=input.nextInt();
        }
        int smallest = numbers[0];
        int largest = numbers[0];

        for(int i=1; i< numbers.length; i++)
        {
        if(numbers[i] > largest)
        largest = numbers[i];
        else if (numbers[i] < smallest)
        smallest = numbers[i];

        }

        System.out.println("Largest Number is : " + largest);
        System.out.println("Smallest Number is : " + smallest);
        }
        }
