第7行和第20行有什么区别?两种情况下线程都会暂停吗?他们执行我的意思相同的任务吗?
I have this schedule :
Operation Line Number
Execution Paused 10 and 20
Start Execution 8
Closing Child Process 21
Thread Creation 7
Execution of Child Process 19
Adjusting Priority 15
Reading Priority 16
还有更多的行吗?例如,在执行暂停时,我们有2行。其他操作也有不止一条线吗?
另外,我的答案正确吗?
答案 0 :(得分:1)
guruthread1.sleep()和Thread.sleep()都在这里做同样的事情-它们暂停主线程。 guruthread1.sleep()是一种误导性的调用,因为sleep()是Thread类的静态方法
