Question

Write a java code that:

1) Takes as an argument an integer number, say N

2) Creates an array of size N

3) Populates the array with random numbers between 0 and 10 * N. This is, the values of the elements of the array should be random numbers between 0 and 10 * N.

4) Finally, the code outputs the index of the smallest element and the index of the largest element in the array

Answer 1

//MinMaxAvg.java
import java.util.Random;
import java.util.Scanner;
public class MinMaxRandomArray {
    public static void main (String[] args) {
        Scanner sc = new Scanner(System.in);
        int n;
        System.out.print("Enter value for N: ");
        n = sc.nextInt();

        Random rand = new Random();
        int arr[] = new int[n];
        for(int i = 0;i<n;i++)
        {
            arr[i] = rand.nextInt(10*n+1);
            System.out.print(arr[i]+" ");
        }

        int minIndex = 0, maxIndex = 0;
        for(int i = 0;i<n;i++){
            if(arr[minIndex] > arr[i]){
                minIndex=i;
            }
            if(arr[maxIndex] < arr[i]){
                maxIndex=i;
            }
        }

        System.out.println("\n\nindex of the smallest element: "+minIndex);
        System.out.println("index of the largest element: "+maxIndex);
    }
}
