What is the difference between java yield () and sleep ()
This article mainly introduces "what is the difference between java yield () and sleep ()". In daily operation, I believe many people have doubts about the difference between java yield () and sleep (). The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the questions of "what is the difference between java yield () and sleep ()"! Next, please follow the editor to study!
Difference
1. Sleep () causes the current thread to pause for a specified time, without the consumption of CPU time slices
2. Yield () is only a hint to the CPU scheduler. If the CPU scheduler does not ignore this prompt, it will lead to thread context switching.
Sleep () temporarily blocks the thread, freeing CPU resources at a given time
If yield () takes effect, yield () moves from the RUNNING state to the RUNNABLE state
Sleep () will almost 100% complete dormancy at a given time, but the hint of yield () does not necessarily guarantee
One thread calls sleep () and another thread calls interrupt () to catch the interrupt signal, while yield does not
Example
Package cn.hanquan.test;/* * sleep simulates a countdown of * / public class Lambda {public static void main (String [] args) {/ / Labmda expression new Thread (()-> {for (int I = 0; I < 100; iSum +) {System.out.println (I); try {Thread.sleep (1000);} catch (InterruptedException e) {e.printStackTrace ();}). Start () }} at this point, the study on "what's the difference between java yield () and sleep ()" is over. I hope I can solve your doubts.
