java - 多线程:我们如何使用 Java 进行时间切片？

Question

是否可以使用内置 java 类来使用 Java 进行时间切片？

当在互联网上搜索时，我仅得到以下类型的定义:

Time slicing is a term which is usually associated with the processor and operating system ... what it means is ... When you have many processes running by an operating system then each process has to get a chance to run ..that is each of the process should get the processor for particular time.....so now if you have 3 processes running eg- p0,p1,p2 then now p0 can run for a time of 5 ms then comes turn for p1 then for p2..... thus you are giving some time called as timeslice to each of the process that has to run by the processor..... Thus there are different algorithms which exists for these processes(depeneds on the operating System) to run on a processor.....

我在 Java 面试问题中遇到了这个问题。但无法获得任何与之相关的 Java 代码示例。

时间切片仅仅是操作系统的概念还是有任何使用 Java 编程来展示的实际用法？有人可以分享同样的例子吗？

Answer 1

int n = Runtime.getRuntime().availableProcessors(); 然后启动 n + 1 个线程。根据定义，如果 n + 1 线程在 n 内核上运行，则发生时间切片。实际使用时，您需要运行 n + 1 个线程，并且只有 n 个 cpu 核心。
