Java console program preventing me from entering string

I am trying to create a simple console program that asks the user if they want to create a list and if so, let them enter the name of the list. Then it should "print" the list name before exiting the program.

My code allows the user to speak y

or n

, for the first part, but in my conditional, it does not allow the user to enter the name of the list; it just ends the program. No error message; it just doesn't function as I expected. Here is my code:

public static void main(String[] args) throws IOException     
{
    getAnswers();
}

public static void getAnswers()throws IOException{
    char answer;
    String listName;        
    BufferedReader br = new BufferedReader 
            (new InputStreamReader(System.in));        
    System.out.println ("Would like to create a list (y/n)? ");

    answer = (char) br.read();        
    ***if (answer == 'y'){
        System.out.println("Enter the name of the list: ");
        listName = br.readLine();
        System.out.println ("The name of your list is: " + listName);}***
    //insert code to save name to innerList
    else if (answer == 'n'){ 
        System.out.println ("No list created, yet");
    }
    //check if lists exist in innerList
    // print existing classes; if no classes 
    // system.out.println ("No lists where created. Press any key to exit")
    }

Thanks in advance for your time and we will help with this!

Change

answer = (char) br.read();

To

answer = (char) br.read();br.readLine();

To read a new line after clicking by the user, y

orn



Complete code:

import java.io.*;

class Test {

    public static void main(String[] args) throws IOException {
         getAnswers();
    }

    public static void getAnswers() throws IOException {
         char answer;
         String listName;        
         BufferedReader br = new BufferedReader(new InputStreamReader(System.in));        
         System.out.println ("Would like to create a list (y/n)? ");
         answer = (char) br.read(); 
         br.readLine(); // <--    ADDED THIS 
         if (answer == 'y'){
             System.out.println("Enter the name of the list: ");
             listName = br.readLine();
             System.out.println ("The name of your list is: " + listName);
         }
         //insert code to save name to innerList
         else if (answer == 'n') { 
             System.out.println ("No list created, yet");
         }
         //check if lists exist in innerList
         // print existing classes; if no classes 
         // system.out.println ("No lists where created. Press any key to exit")
    }
}

Ouput:

Would like to create a list (y/n)? 
y
Enter the name of the list: 
Mylist
The name of your list is: Mylist

Is this the result you expect?

The problem is read (). it doesn't read the newLine that comes from Enter.



 answer = (char) br.read();        // so if you enter 'y'+enter then -> 'y\n' and read will read only 'y' and the \n is readed by the nextline.
    br.readLine();    // this line will consume \n to allow next readLine from accept input.

...
String answer = br.readLine ();
if (answer.startsWith ("y")) {
