core java developer resume

Java was originally staged in browsers and client machines. At the time, many people questioned whether it was suitable for server-side development. Now, with the increase in Third-party support for the JAVA2 platform Enterprise version, Java is widely accepted as one of the preferred platforms for developing enterprise server-side solutions. In this article I will explain 13

reflected. On systems using Intel processor hyper-Threading Technology (HT technology), there are currently two execution pipelines on each processor core. The latest multi-core processor has two processor cores on each chip. Intel pointed out that chips may have multiple cores in the future, most of which are due to higher performance and will not fundamentally increase the consumption of heat or power. T

requires the developer to manually release, must be released in final, otherwise it will cause a deadlock. At the same time, lock () has a more powerful function than synchronized (), and its Trylock () method can acquire locks in a non-blocking manner.Although both synchronized and lock can achieve multi-threaded synchronization, it is best not to use both locks at the same time, because the mechanisms of the two locks are different, they are run in

This is because at that point, other threads may be running and not scheduled to abort execution unless (a) the "Wake Up" thread has a higher priority(b) The running thread is blocked for other reasons.When wait () is a thread interaction, if the thread makes a wait () call to a s
