Notice that work() is an abstract method and it has no-body. Here is a concrete class example extending an abstract class in java. package com.journaldev.design; public class Employee extends Person { private int empId; public Employee(String nm, String gen, int id) { super(nm, gen); ...
abstract class X implements Y { // implements all but one method of Y } class XX extends X { // implements the remaining method in Y } In this case, class X must be abstract because it does not fully implement Y, but class XX does, in fact, implement Y. Class Members An abstrac...

AQS 又称为队列同步器,java 是通过 AbstractQueuedSynchronizer 类来实现其思想的。 他通过一个 int 类型的成员变量 state 来控制同步状态,state = 0 时,则说明没有任何线程占用锁,当 state = 1 时,则说明有一个线程目前正在占用锁。 它支持实现共享锁与独占锁,下面我们就从源码来剖析,分析一下 AQS 的实现原...
