Question

I am doing the daily challenges from /r/dailyprogrammer and am working on the very first one. I am trouble with the final output printing before taking in the input of rUserName. How would I delay this until it had the input?

import java.util.Scanner;

public class Easy1 {

   public static void main(String args[])

   {

       Scanner keyboard = new Scanner(System.in);

       String name;

       int age;

       String rUserName;

       // Ask for users name

       System.out.println("Enter your name.");

       name = keyboard.nextLine();

          // Ask for users age

       System.out.println("Enter your age.");

       age = keyboard.nextInt();

       // Ask for reddit user name

       System.out.println("Enter your reddit user name.");

       rUserName = keyboard.nextLine();

       // Tell user their name, age, and username.

       System.out.println("Your name is " + name + ", your age is " + age + ", and your reddit username is " + rUserName);

   }

}

Explanation / Answer

add just keyboard.nextLine() after age=keyboard.nextInt(); It will then work...

The problem is with the keyboard.nextInt() command it only reads the int value. So when you continue reading with input.nextLine() you receive the " " i.e new line and Enter key. So to skip this you have to add the keyboard.nextLine()
