Lab Objectives This lab was designed to reinforce programming concepts from this lab, you will practice: • Declaring and initializing arrays. • Comparing input to array elements. • Preventing array out-of-bounds errors. The follow-up questions and activities will also give you practice: • Initializing array sizes during program execution. • Generalizing programs. Description Use a one-dimensional array to solve the following problem: Write an application that inputs five numbers, each of which is between 10 and 100, inclusive. As each number is read, display it only if it is not a duplicate of a number already read. Provide for the “worst case,” in which all five numbers are different. Use the smallest possible array to solve this problem. Display the complete set of unique values input after the user inputs each new value. Sample Output Enter number: 11 11 Enter number: 85 11 85 Enter number: 26 11 85 26 Enter number: 11 11 has already been entered 11 85 26 Enter number: 41 11 85 26 41

this is a java code do it in eclipse please. thank you.

Answer:

import java.io.*;
import java.util.*;
public class Main
{
   public static void main(String[] args) {
       int num[]=new int[5]; //array num of size 5
       int temp=0,count,k=0;
       Scanner s=new Scanner(System.in);
       for(int i=0;i<5;i++) //this loop will make sure to enter 5 numbers each of which is b/w 10 and 100
       {
       count=0; //this is to increment if duplicate is found
       System.out.print("Enter number:");
       temp=s.nextInt();
       while(temp<10 || temp>100){ //this loop will take care to enter element b/w 10 and 100
       System.out.println("number should be b/w 10 and 100");
       System.out.print("Enter number:");
       temp=s.nextInt();
       }
       for(int j=0;j<k;j++) //comparing input to elements in array
       {
       if(temp==num[j])
       {
       count++;
       System.out.print(temp+" has already been entered ");
       }
       }
       if(count==0)
       {
       num[k]=temp; //input is stored into array only if no duplicate is foundd
       k++; //k is used for indicating number of values stored in to array
       }
       for(int l=0;l<k;l++)
       {
       System.out.print(num[l]+" "); //this is for printing elements
       }
       System.out.println();
       }
   }
}

OUTPUT:

Enter number:11 Enter number:85 11 85 Enter number:26 11 85 26 Enter number:11 11 has already been entered 11 85 26 Enter number:41 11 85 26 41

Enter number:10 10 Enter number: 100 10 100 Enter number:9 number should be b/w 10 and 100 Enter number:11 10 100 11 Enter number:11 11 has already been entered 10 100 11 Enter number:12 10 100 11 12

you could see here it increments value of k only if it is between 10 and 100 such that values entered less than 10 and greater than 100 are invalid.
