Yesterday I wrote about the concurrency problem caused by multithreading and the solution-lock. Then let's continue today...I. Concurrent analysisJava has a concept called producer and consumer.Assume that the producer continuously produces apples
Thread. currentThread ()Public static native Thread currentThread () to determine which thread is executing a segment of code execution of the methods in Thread are listed with some of the following modifiers: native, final, static, and synchronized.
Thread creation and startup The Java language has built-in multi-thread support. All classes that implement the runnable interface can start a new thread. The new thread will execute the run () method of the instance. When run () after the method

I. Overview
Because Java is a pure object-oriented language, the Java thread model is also object-oriented. Java encapsulates all the functions required by the Thread through the Thread class. To create a Thread, you must have a Thread to execute

the two ways that Java implements multithreading are to inherit the thread class and implement the Runnable interface, respectively. code example:Class MyThread extends thread{private String name; Public MyThread (String name) { this.name = name;}

Before Java 5, the use of the Synchronized keyword to implement the lock function.
The Synchronized keyword can be used as a modifier for a method (a synchronization method) or as a statement within a function (a synchronized code block).
Master
As we all know, before JDK1.5, Java in the business concurrency, often need to have the programmer to complete the code implementation, of course, there are some open source framework to provide these features, but these still do not have the

A Two major problems in network programming
One is how to accurately locate the network on
