50 Java Thread Surface questionsHere are some popular interview questions about Java threading, which you can use to prepare for the interview.1) What is a thread?A thread is the smallest unit that the operating system can perform operations on, which is included in the process and is the actual operating unit of the process. Programmers can use it for multiprocessor programming, and you can speed up operations-intensive tasks using multithreading. Fo

Lenovo's projection phone can project touch screen to any surfaceSmart machines with built-in projectors-well, there's really only two of Samsung's--so far not really popular, but Lenovo thinks it finally found this combination of the right use case: Project a touch screen or a virtual keyboard to your desktop.

multithreading problems such as producer consumers, philosophers dining, A reader or a simple bounded buffer problem. Just knowing the basic concept of threading is far from enough, you must know how to deal with the concurrency problems such as deadlock, race condition, memory conflict and line Cheng. With these tips, you can easily handle multithreading and concurrent interviews. It's normal for many Java programmers to go to the interview before the interview. Because collecting face questio
