I have a main class that starts two threads that write some charachers on the screen.
If I add a System.out.print("something") after the two start commands that something appear before the characters that the threads output yo the screen?
Why so?
Thank you very much.

"skiabox", welcome to JavaRanch. We're a friendly bunch here, but we do require our ranch hands to use real screen names. You can read the policy here.

So please change your screen name to a real name. You can do that here. And be aware that not following the policy may lead to termination of your account.

Don't understand the question, I am afraid. Please supply more details, eg what you are printing on screen.

You do realise that the two Threads run independently of each other, so they will not necessarily carry out actions in a particular order, particularly things like input and output which can take thousands or millions of times longer to execute than calculations?

There's no telling which of the 3 threads will be scheduled to run (or to be started) first. The results could be different on different machines, or on different JREs on the same machine, and even on the same JRE on the same machine (although that's unlikely).
 
I agree. Here's the link: http://aspose.com/file-tools
