wait只能在同步(synchronize)环境中被调用,而sleep不需要。详见Why to wait and notify needs to call from synchronized method 进入wait状态的线程能够被notify和notifyAll线程唤醒,但是进入sleeping状态的线程不能被notify方法唤醒。 wait通常有条件地执行,线程会一直处于wait状态,直到某个条件变为真。但是sleep仅仅让你...
了解多线程中的yield 最近在学习多线程这一块,发现里面有好多让人产生误区的地方,今天我来分析下java多线程中的yield功能,希望其他朋友也可以从中学习到相关知识。 开始之前先看下面一幅图: 这幅图表示线程的运行状态:新建---》就绪《--阻塞--》运行---》死亡 yield从字面上看是礼让的意思,顾名思义就是让其...

The ‘yield’ and ‘return’ keywords in Java serve distinct purposes and are used in different contexts. Areturnstatement returns control to the invoker of a method or constructor. Ayieldstatement transfers control by causing an enclosingswitchexpression to produce a specified value. ...
