Use of hasNextLine in Java, won't read NextLine after NextInt

Question

Hey guys and gals,

I am trying to get this to work

 System.out.println("Please enter what SOCKET NUMBER you" + 
"wish to connect to");   
            int sockname = Integer.parseInt(inFromUser.nextLine());

   System.out.println("Please enter what HOSTNAME you" + 
"wish to connect to");
   String hostname = inFromUser.nextLine();

The problem is that I can't get hostname to equal whatever the user input. I thought it had to do with hasNext or a variant of that, but I'm not sure. Any thoughts?

Answer 1

java.io.BufferedReader has a readLine() method. Use that. If you're using Scanner.nextLine(), then you should know that if your position is just before a newline, you'll get an empty string. However, the next nextLine would indeed return a full line of text (the same as readLine would).

Answer 2

There might be "\n" in the input buffer after nextLine(), so next call just reads it and returns. You need to clear the buffer after reading int

inFromUser.skip("\\n+");
