java 多线程和线程池

● 多线程多线程的概念很好理解就是多条线程同时存在，但要用好多线程确不容易，涉及到多线程间通信，多线程共用一个资源等诸多问题。使用多线程的优缺点：优点： 1）适当的提高程序的执行效率（多个线程同时执行）。 2）适当的提高了资源利用率（CPU、内存等）。缺点： 1）占用一定的内存空间。 2）线...

请教java多线程问题

正常来说，一个线程start后的默认名字是Thread,`t.start();t.setName();`这时可以修改线程名，而且可以多次setName，看了源代码也没懂为什么，求高手指导

新手学JAVA（十）-多线程----线程的创建和启动

Java使用Thread类代表线程，所有的线程对象都必须是Thread类或者其子类的实例。每个下次你哼的作用是完成一定的任务，实际上就是执行一段程序流（一段顺序执行的代码）。Java使用线程执行体来代表这段程序流在Java线程的创建有三种方式&nbs...

JAVA之旅（十五）——多线程的生产者和消费者，停止线程,守护线程,线程的优先级，setPriority设置优先级，yield临时停止我们接着多线程讲一.生产者和消费者什么是生产者和消费者？我们解释过来应该是生产一个，消费一个，的意思，具体我们通过例子来说 package com.lgl.he...

java多线程并发问题求解

父类中定义了几个成员变量String类型 a，b，c，这个父类被几个子类共同继承了，各个子类中在构造器内初始化了a,b,c变量，问多线程调用每一个子类时会产生并发问题吗？
