Here is a code that accepts the number and compare the number with the array. If the number exists in the array, the code displays that number.

import java.util.*;

class Compare { 
    public static void main(String []args) { 
        int idno[] = {1,2,3,4,5,6};
        int input;
        int no=0;
        System.out.print("Enter no: ");
        Scanner scan = new Scanner(System.in);
        input = scan.nextInt();
        for(int i=0;i<idno.length;i++){
        if(input == idno[i]) { 
            no=input; 
            } 
        }
        System.out.println(no);
    }
}
