advantage of using thread

[Abalfazl]

The key in using threads to simplify your code is to try to keep your functions and methods on one train of thought. Rather than turn your code into an arthritic mess trying to interleave multiple simple simultaneous tasks, code each task separately. Code each line block with one mind. Let the OS thread scheduler do the interleaving.

What do you understand from this?

[ProgramThis]

Are you asking yourself what you understand from that, or trying to bump your thread?

I understand it just fine, what do you not understand about it? Asking a question like "what do you understand from this" isn't a really good question to ask.

1-Is it the Os or is it the JVM choose which thread to run?

2- What is the relationship between JVM and OS thread scheduler ?

Have you tried Googling for the answers to these questions? Have you tried searching this forum for the answers (hint) ?

They sound very much like homework assignment questions that you're expected to discover for yourself.

I might be inclined to help if you tell me what you've discovered for yourself and explain why it isn't enough for you, or what it is you don't understand.

The outcome of any serious research can only be to make two questions grow where only one grew before...

Scheduler is part of OS or Java Virtual Machine (JVM)

May you explain more about mechanism of Scheduler?

[dlorde]

Try this.

One can think effectively only when one is willing to endure suspense and to undergo the trouble of searching...

VM to OS Thread Mapping

The way Java threads are mapped to OS threads is up to the JVM and its use of multiple processors on a machine. Different JVMs use different strategies:

Some JVMs use green threads, running all Java threads in one native OS thread (called n-to-one mapping). Sun's HotSpot JVMA website external to this site uses native threads, which may execute in parallel on a multi-CPU machine. On Solaris, Java threads are not bound permanently to the same native threads but are remapped by the scheduler (in an n-to-m mapping).

1-What is thread mapping?

2-What is native thread?What its difference with green thread?

You really need to learn how to use search engines, and think for yourself - reread what you just quoted, and think about it.

The Internet? Is that thing still around?
