You are using lower case 'l' (L) which is not correct. What you need is capital letter 'I' as Integer.parseInt(...).

You didn't obtain the value reading from the user. Also, even you did that, your program will accept an input from a user only once and display the result. Your current score is 0 for your display (vote). You just take the value of the initial value of 'vote' to your 'x'. The showInputDialog() returns a string of the … Re: Menu option 13 Years Ago by mKorbel and if you don't like if-else-if-else ...., then just for Integer instance: [CODE] switch (integer) { case 1: //some stuff case 2: //...... case 3: // ... case 4: //... default: System.out.println("someWarning"); }[/CODE] Re: Menu option 13 Years Ago by Taywin The problem is your 'outputString' is not being assigned to anything. The reason I did not write anything inside the if-else statement because I wanted to see how much you understand the code. Anyway, it seems that you are still unclear about it. So the way to fix this is to append your outputString with those string you use in System.out.println… Re: Threads - need little help 15 Years Ago by Alex Edwards I don't think it's the run method that isn't executing, Peter. I think the problem is that you are not submitting a Runnable target as the argument for the Thread to execute. I actually don't understand why the Thread class is not abstract if it allows one to simply give a Thread a title, but I will investigate this a bit more thoroughly and … Re: Threads - need little help 15 Years Ago by Ezzaral Yes, the Threads in your example don't really do anything. You need to extend Thread and override run() or supply a Runnable to the constructor. Have you looked through the tutorial on concurrency as a starting point?

You describe wanting to process another song after the current one is finished, but haven't mentioned anything that would require a concurrent process. Re: Threads - need little help 15 Years Ago by Ezzaral Just to answer the question on waiting for one thread to finish before starting the next, here's a trivial example using the join() method[code=java] public class JoinExample { public static void main(String args[]) { Thread t1 = new Thread(new FirstTask()); Thread t2 = new Thread(new SecondTask()); t1.… Re: Threads - need little help 15 Years Ago by peter_budo Thanx guys, I will play around with these examples.

Current state of JSR-135: Mobile Media API still need lot of work.
