Thread: Help with my simple Scanner program?

Hello all,
I am new to the forum and am seeking some help on why my program is not working as expected . For some reason, my program skips over letting the user enter their town. I would be very grateful for any help that one may provide me with:

import java.util.Scanner;
 
public class Okay
{
  public static void main(String[] args)
  {
    String name, town;
    int age, siblings;
    Scanner details = new Scanner (System.in);
 
    System.out.println("Hey, what's your name?");
    name = details.nextLine();
 
    System.out.println("That's cool my friend is named " + name + " too!");
    System.out.println("How old are you?");
 
    age = details.nextInt();
    System.out.println("Wow, my friend, " + name + ", is " + age + " years old" +
                       " too!");
    System.out.println("What town do you live in?");
 
    town = details.nextLine();
 
    System.out.println("This is getting kind of crazy... My friend, " + name +
                       " lives in " + town + ", too!");
    System.out.println("How many siblings do you have?");
 
    siblings = details.nextInt();
 
    System.out.println("STOP RIGHT THERE. THIS IS INSANE. My friend, " + name +
                       ", has " + siblings + " siblings, too!!!");
 
    System.out.println("Wait, " + name + ", is that YOU!?");
 
 
  }
}

That is because of the nextInt() method that you have used, you have read the number,
but you have not skipped the line of the user's input,
to avoid the bugs insert this code after you used nextInt() method.
details.nextLine(); that will help your program to skip the line.
hope that will help

Thank you very, very much, adding details.nextLine(); fixed the problem!

Is this due to the newline('\0') being left in the buffer after the user enters in the int?

the nextLine() method advances the scanner past the current line.
I think the nextInt() method cannot do that..

kindly see this link Scanner (Java Platform SE 7 )
