Write an expression that will cause the following code to print "18 or less" if the value of user_age is 18 or less. Write only the expression. Sample output with input: 17 18 or less

if (user_age<=18){

           System.out.println("18 or less");

       }

Explanation:

The above expression in Java will print "18 or less" if the input is less than 18.

Consider a complete java program that request a user to input his/her age below and prints "18 or Less" if the user age is less or equal to 18.

import java.util.Scanner;

public class num2 {

   public static void main(String[] args) {

   Scanner in = new Scanner(System.in);

       System.out.println("enter age:");

       int user_age =in.nextInt();

       if (user_age<=18){

           System.out.println("18 or less");

       }

       else

       {

           System.out.println("greater than 18");

       }

   }

}

answer; insolated i/o uses separate memory space,and on the other hand memory mapped i/o uses memory from the main
