How can I effectively use JMH for benchmarking in Java?

JMH, or Java Microbenchmark Harness, is a framework for benchmarking Java code. It helps you measure the performance of your code accurately.

What are the basic steps to set up a JMH project?

To set up a JMH project, you need to add the JMH dependency to your build tool, create a benchmark class, and annotate your methods with @Benchmark.

Can you give me an example of a simple benchmark?

Sure! Here's a simple example:

@Benchmark
public void testMethod() {
    // Your code to benchmark
}

How do I run the benchmarks once they're set up?

You can run the benchmarks by executing the main method in your benchmark class. JMH will handle the rest and provide you with the results.
