RecallNoIF!

Write a program named RecallNoIF that reads an integer representing a year. (In this case there is no prompt from the program.) The program prints out RECALL if the year was 2004, 2010 or 2015 and NO RECALL otherwise.

Sample Interactive Run 1:

2010
RECALL

Sample Interactive Run 2:

2012
NO RECALL

Answer 1

Java program prompts the user to enter the input year value then check if input year is 2004 or 2010 or 2015 then print RECALL otherwise print the NO RECALL on java console window.

//RecallNoIF.java
//import Scanner class
import java.util.Scanner;
public class RecallNoIF
{
   public static void main(String[] args)
   {
       //Create an object of Scanner class
       Scanner kboard=new Scanner(System.in);
       //declare an integer variable, inputYear
       int inputYear;
       //read an integer value from keyboard
       inputYear=Integer.parseInt(kboard.nextLine());
       //Ternary operator
       //(Condition )? (expression1 if condition is true) : (expression2 if condition is false)
       //Check if inputYear is 2004 or 2010 or 2015
       //Then set the result to RECALL otherwise set result to NO RECALL
       String result=(inputYear==2004 ||inputYear==2010 ||inputYear==2015)?
               "RECALL":"NO RECALL";
       //print result on java console
       System.out.println(result);

   } //end of main method
} //end of the class,RecallNoIF
