IN java

Create a New Java Project called LastNameDuplicate.

//Given an array of N elements with each element between 1 and N, write a program to determine whether there are any duplicates.

//You must prompt the user for the array elements.

//Display the contents of the array, along with the values that are duplicated and how many times they appeared in the array.

//NOTE: N should be at least 15. Input Validation: Verify that each element entered has a value between 1 and N. If an incorrect value is entered, continuously prompt for a new value. This should not halt or terminate your program.

Java Program:

/* Java Program that reads elements in to array and displays duplicate count */

import java.util.*;

class Duplicates

   public static void main(String args[])
   {
       Scanner sc = new Scanner(System.in);

       //Reading integers from the console
       System.out.println("\n Enter array elements: ");

       for (i = 0; i < N; i++)

Java programming language: 1. Create a new Netbeans project called ArrayLoop. 2. Declare a fixed length array of integers which can store 8 elements. Do not assign any values. int[] myAddresses = new int[8]; 3. Create a statement which raises 2 to the power of your loop counter, then subtracts 1, and assigns that value to the corresponding element. For example, when i = 3, 2 to the third power is 8, minus 1 = 7. When i = 4, 2 to the...
