概念 我们知道 start() 方法是启动线程,让线程变成就绪状态等待 CPU 调度后执行. 那 yield() 方法是干什么用的呢?来看下源码. /** * A hint to the scheduler that the current thread is willing to yield * its current use of a processor. The scheduler is free to ignore this * hint. * * <p> Yield is a heu…
先上一段代码 public class YieldExcemple { public static void main(String[] args) { Thread threada = new ThreadA(); Thread threadb = new ThreadB(); // 设置优先级:MIN_PRIORITY最低优先级1;NORM_PRIORITY普通优先级5;MAX_PRIORITY最高优先级10 threada.setPriority(Thread.MIN_PRIORITY);…

这是Java中的一种线程让步方法,让Java中的线程从执行状态变成就绪状态,然后处理器再从就绪队列中挑选线程进行执行(优先级大的,被挑选的概率较大),这种转换也不确定,让或者不让都是取决与处理器,线程可能继续占有处理器. ** * A hint to the scheduler that the current thread is willing to yield * its current use of a processor. The scheduler is free to ignore…
