**How to find unique elements in array java**

Write a java program that inputs 5 numbers, each between 10 and 100 inclusive. As each number is read display it only if it‘s not a duplicate of any number already read display the complete set of unique values input after the user enters each new value.

### Description :

The main two conditions of these programs are

- A number once read should not be read again.
- The number we read should be in the range of 10 and 100.

**The logic is as follows**

- If the number lies between 10 and 100,

Compare the recently read number with all the previously read numbers, if any number matches then declare that it a duplicate and ask the user to enter another number. Else declare that the number is not in the range of 10 and 100 and read another number.

### Algorithm:

- import java package
- import java.io.*;
- import java.util.*;

- Create class Array
- create main function
- public static void main(String ar[])

- Declare variable
- int temp, i, flag = 0;
- int a[] = new int[10];

- Scanner s = new Scanner(System.in);
- Pass message to enter values
- System.out.println(” Enter values: “);

- Use for loop and write a statement and also perform the comparison.
- for( i = 0; i<5;)
- term = s.nestInt();
- flag = 0;
- if (temp > 10 && temp < 100)
- for int j= 0; j++)
- if (a[j] == temp)
- flag = 1;

- if (a[j] == temp)
- if( flag == 0);
- a [i] = temp;
- i++;

- else Print Number already exist, enter another value:
- else print number not in range

- for int j= 0; j++)
- Print Number in the array are:

- for( int j = 0; j < 5; j++)
- print a[j];

### Program to find Unique Array Element Source code:

import java.io.*; import java.util.*; public class Arrayy { public static void main(String ar[]) { int temp,i,flag=0; int a[]=new int[10]; Scanner s=new Scanner(System.in); System.out.println("Enter values : "); for( i=0;i<5;) { temp=s.nextInt(); flag=0; if(temp>10 && temp<100) { for(int j=0;j<i;j++) if(a[j]==temp) flag=1; if(flag==0) { a[i]=temp; i++; } else System.out.println("Number already entered. Enter another value : "); } else System.out.println("Number not in range. Enter another values : "); } System.out.println("Numbers in the array are : "); for(int j=0;j<5;j++) System.out.println(a[j]); } }
