java - multithreading

Google: Java + thread.

Threads (first result)

Multithreading is always enabled all the time, in fact it is essential to the JVM as it processes certain things on different threads.

Two ways to write a thread, overload the Thread class or implement the Runnable interface. I suggest the latter.

some class must implement the Runnable interface. You pass an instance of that class to the constructor of the Thread class. You then call the start method of that instance of the Thread class. That's all you have to do, it's really easy.

also, this belongs in the Java Forum.

Original post by CodeEnthusiast I just started Java and have a question about its multithreading. I've heard it is built-in, is that correct? And also, if it is, do I need to do anything special to "activate" this multithreading like in C or C++ or does it automatically do that for you? Any answers would be appreciated.

Be careful: Java threads are frequently the source of many difficult-to-find bugs. This is also true of any asynchronous/nondeterministic programming model, of course, but Java threads have their own unique problems. Googling on Java threading bugs should reveal some choice examples.
