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. (Java language)

Answer 1

import java.util.Scanner;
public class MinimumOfArray
{
   public static void main (String[] args)
   {
      
       int min,max;
      
       Scanner sc = new Scanner (System.in);
       System.out.print("Enter Number of elements: ");
       int n=sc.nextInt();
       System.out.print("Enter Array elements: ");
       int[] arr=new int[n];
       for(int i=0;i<n;i++)
       {
           arr[i]=sc.nextInt();
       }
      
       System.out.println("Array is: ");
       for(int i=0;i<n;i++)
       {
           System.out.print(arr[i]+" ");
       }
       System.out.println();
       min = findmin(arr);//functions are called
       System.out.println("Smallest is: "+min);
      
       max = findmax(arr);//functions are called
       System.out.println("Largest is: "+max);

      
   }//end of main method
   public static int findmin(int arr[])
   {
       int min=arr[0];
       for(int i=0;i<arr.length;i++)
       {
           if(arr[i]<min)
               min=arr[i];
       }
       return min;
   }
   public static int findmax(int arr[])
   {
       int max=arr[0];
       for(int i=0;i<arr.length;i++)
       {
           if(arr[i]>max)
               max=arr[i];
       }
       return max;
   }
}
