Question

Complete the Java code. The code should print “x is in numbers” if the integer x is one of the values stored in numbers. If x is not in numbers, your code should print “x is not in numbers”

public static void main(String[] args){

                        int[] numbers = <some array values>;

                        int x = <some value>;

            }

Answer 1

The code is done in Java and it is simply understandable and for more clarity it is comments have been added.

CODE:

/* package whatever; // don't place package name! */

import java.util.*;
import java.lang.*;
import java.io.*;

/* Name of the class has to be "Main" only if the class is public. */
class Ideone
{
   public static void main (String[] args) throws java.lang.Exception
   {
       // array consisting numbers
       int[] numbers = { 12, 11, 13, 5, 6 };
       //finding the length of array
       int n = numbers.length;
       //number to be searched
       int x = 13;
       //variable to keep track of number present in array or not
       int flag=0;
       //traversing the array from index 0 to n-1
       for(int i=0;i<n;i++){
           //checking the condition
           if(numbers[i]==x){
               System.out.print(x + " is in numbers ");
               flag=1;
               break;
           }
       }
       //checking the condition of element not present in array
       if(flag==0){
           System.out.print(x + " is not in numbers ");
       }
   }
}

OUTPUT:

Success #stdin #stdout 0.08s 33884KB

13 is in numbers
