Introduction

Measuring code execution time is a vital step in trying to write efficient applications. Temporal awareness of your code on a machine that might be serving a great deal of users lets you plan further, accounting for the execution time.

In multi-threaded systems, it’s also useful to measure the execution time of individual Threads or asynchronous tasks.

Since there’s no built-in, convenient way to measure code execution in Java - for Spring-based solutions, we’ve been introduced to the StopWatch tool.

In this tutorial, we’ll take a look at _how to measure code execution time in Java with Spring’s __StopWatch_.
