Java线程示例 (Java Thread Example) This is the first post in the multithreading in java tutorial series. Read this to learn about Process and Thread. What is the difference between Thread and Process. Benefits of using Threads and how we can create Threads using Runnable interface and Thread c...
Java多线程(multithreading),是指从软件或者硬件上实现多个线程并发执行的技术。多线程能够提高资源的利用率而在java线程中独具优势,归功于java多线程的三大特性。 原子性 Java的原子性其实和数据库事务的原子性差不多,即一个操作或者多个操作,要么全部执行并且执行的过程不会被任何因素打断,要么就都不执行。由此及彼,...

进程是通常彼此独立运行的程序的实例。例如,如果启动Java程序,则操作系统会产生一个新程序,该程序process(进程)可与其他程序并行运行。在这些进程中,我们可以利用线程并发执行代码,因此我们可以充分利用CPU的可用内核。 与线程不同,进程不会彼此共享资源。process(进程)是资源的单位,而thread(线程)是调度和执行的单位。
线程创建和管理: 在Java中,可以使用java.lang.Thread类创建线程,并通过调用start()方法启动线程。而在C/C++中,可以使用C库中的pthread库创建线程,并通过调用pthread_create()函数启动线程。 线程同步和互斥: Java中可以使用java.util.concurrent.locks包中的锁对象(如ReentrantLock)来实现线程同步和互斥。而在C/C++中...
