Java Package quick start tutorial Why is Java Package designed? If you have never thought about it, I may provide a perspective here. Imagine that, as a language designer, you must consider the conflict of variable names. To solve this problem, C ++ introduced namespace and Java introduced package.1. variable name conf

Java thread: A thread is the sequential control flow within a program. The CPU actually executes only one task at a time point. However, we divide the CPU into multiple time slices. Because of the high speed, we seem to have multiple threads .. Just like dividing your time into several slices, it seems that the efficiency will be high if you do things regularly, not to mention the cup. Thread creation and startup: Method 1:

For both paragraphs are direct new thread to create an anonymous class object, you can define a variable thread1, thread2, and then use Thread1.start () Thread2.start () to start the thread; SOURCE Analysis What's the difference between the two, the final effect is the same, at the source level, the default run method of thread (not overwritten) is the Ru

Creation and initiation of threads The Java language has built-in multithreaded support, and all classes that implement the Runnable interface can be started with a new thread that executes the run () method of the instance, and the thread ends when the run () method finishes executing. Once a thread has finished executing, the instance can no longer be restarted, only a new instance can be rebuilt, and a new thread is started. The thread class is a

one by one, the only change is that the lightweight process is no longer tied directly to the process, but is linked to the user thread, User threads do not necessarily have to correspond to lightweight process one by one, but are many-to-many, as with a lightweight process list, which adds a layer of decoupling between lightweight processes and the original process, which may make scheduling more flexible. In the previous JDK version, tried to use UT to implement, but later gave up, with
