This article explains several common techniques for measuring Java code execution time, including System.currentTimeMillis(), Spring's StopWatch utility, System.nanoTime(), and the use of new Date(), providing code examples and a brief overview of StopWatch's API for developers seeking precise performance metrics.
This article explains how to quickly benchmark Java code performance, introduces the JMH microbenchmarking tool, provides sample JMH benchmark code comparing System.currentTimeMillis() and System.nanoTime(), and presents the results showing nanoTime's superior throughput.
This article introduces six practical methods for measuring Java code execution time, covering built‑in System.currentTimeMillis, System.nanoTime, new Date, Spring’s StopWatch, Apache Commons‑lang3 StopWatch, and Guava’s Stopwatch, and explains their underlying principles and usage examples.
