在IntelliJ IDEA中检查运行时间 [英] Checking Run time in IntelliJ IDEA

问题描述

如何查看在InteliJ中运行代码需要花费多少时间?

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

推荐答案

我认为您无法使用Intellij，您必须使用 Yourkit 这样的分析器来分析代码或使用一些 System.currentTimeInMillis()使用原始基准测试.另外，您可以使用 Apache Commons StopWatch 进行一些基准测试:

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

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

Intellij有一个可用VisualVM进行性能分析的插件，您可以将其安装为另一种选择.

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