Question

1. Write a program that computes the smallest and largest of a set of values that are stored in an array. Ask the user for the set size (and hence the array size). Populate the array with user input.

Answer 1

import java.util.Scanner;

public class Main
{
   public static void main(String[] args) {
   Scanner sc=new Scanner(System.in);
   System.out.print("Enter the size of array:");
   int n=sc.nextInt();
   int a[]=new int[n];
  
   for(int i=0;i<n;i++){
System.out.print("Enter the element"+(i+1)+":");
a[i]=sc.nextInt();
   }

int minimum=a[0];int maximum=a[0];
for(int i=0;i<n;i++){
if(a[i]<=minimum)
minimum=a[i];
if(a[i]>=maximum)
maximum=a[i];
}
System.out.println("smallest number in array:"+minimum);
System.out.println("largest number in array:"+maximum);

   }
}
