I'am reading multithreading and am unable to understand this point.it says
"java uses threads to enable the environment to be asynchronous".
this is quite contrary to what i basically understood. well the other term for threads is concurrency. any program is asynchronous. where each part of the code oocurs at different times or in a sequence. the only advantage is memory allocation and the context switch to promote efficiency. what is the point they are trying to make by that sentence. can you please explain.
I think that you may be mixing terminology. I believe, when the term "asynchronous" is used here, it is referring to asynchronous behavior -- such as asynchronous I/O. I don't think it is referring to the opposite of thread synchronization.
