Checking Run time in IntelliJ IDEA

javatimeintellij-idea

提问by Eran

How can I see how much time it took for the code to run in InteliJ?

如何查看代码在 InteliJ 中运行所需的时间?

采纳答案by Jon

I don't think you can with Intellij, you either have to use a profiler like Yourkitto profile the code or use some primitive benchmarks using System.currentTimeInMillis(). Alternatively you can use Apache Commons StopWatchto do some benchmarking:

我认为您不能使用 Intellij,您要么必须使用像Yourkit这样的分析器来分析代码,要么使用System.currentTimeInMillis()使用一些原始基准。或者,您可以使用Apache Commons StopWatch进行一些基准测试:

StopWatch stopwatch = new StopWatch();
stopwatch.start();
... some code...
stopwatch.stop();
long timeTaken = stopWatch.getTime()

EDIT: There is a plugin available for Intellij that uses VisualVM to do profiling, you could install this as another alternative.

编辑:有一个可用于 Intellij 的插件,它使用 VisualVM 进行分析,您可以将其安装为另一种选择。
