Write a Java program that asks the user to enter an array of integers in the main method. The program will ask the user for the number of integer elements to be put in the array, and then ask the user for each element of the array. The program then calls a method named isSorted() that accepts an array of integers and returns true if the list is in sorted (increasing) order and false otherwise. For example, if arrays named arr1 and arr2 store [10, 20, 30, 41, 56] and [2, 5, 3, 12, 10] respectively, the calls isSorted(arr1) and isSorted(arr2) should return true and false respectively. Assume the array has at least one integer element. A one-element array is considered to be sorted.

The program is as follows:

import java.util.Scanner;

public class MyClass {

   public static Boolean isSorted(int [] arr){

       Boolean sorted = true;

       for(int i = 0;i<arr.length;i++){

       for(int j = i;j<arr.length;j++){

           if(arr[i]>arr[j]){

               sorted = false;

               break;

           }

       }    

       }

       return sorted;

   }

   public static void main(String args[]) {

       Scanner input = new Scanner(System.in);

       int n;

       System.out.print("Length of array: ");

       n = input.nextInt();

       int[] arr = new int[n];

       System.out.println("Enter array elements:");

       for(int i = 0; i<n;i++){

           arr[i] = input.nextInt();

       }

      Boolean chk = isSorted(arr);

     System.out.print(chk);

   }

}

Explanation:

The method begins here

This line defines a method named isSorted

   public static Boolean isSorted(int [] arr){

This line declares a boolean variable and initializes it to true

       Boolean sorted = true;

The next two iterations iterate through elements of the array

       for(int i = 0;i<arr.length;i++){

       for(int j = i;j<arr.length;j++){

This compares an array element with next elements (to the right)

           if(arr[i]>arr[j]){

If the next element is smaller than the previous array element, then the array is not sorted

               sorted = false; The boolean variable is updated to false

               break; This breaks the loop

           }

       }    

       }

This returns true or false, depending on the order of the array

       return sorted;

   }

The main method begins here

public static void main(String args[]) {

       Scanner input = new Scanner(System.in);

       int n;

This prompts user for length of array

       System.out.print("Length of array: ");

This gets length of array from user

       n = input.nextInt();

This declares an array

       int[] arr = new int[n];

This prompts user for array elements

       System.out.println("Enter array elements:");

The following iteration gets the array elements

       for(int i = 0; i<n;i++){

           arr[i] = input.nextInt();

       }

This calls the isSorted array      

     Boolean chk = isSorted(arr);

This prints true or false, depending if the array is sorted or not

     System.out.print(chk);      

   }

system programmer option d is correct

because an operating system is software that manages computer hardware and system resources.
