How can I optimize my Java code using JMH?

You can optimize your Java code by using the Java Microbenchmark Harness (JMH) to measure performance accurately.

What are the key features of JMH that help in performance optimization?

JMH provides features like warm-up iterations, different benchmarking modes, and detailed reporting to help you analyze performance.

Can you give me an example of a simple benchmark using JMH?

Sure! Here's a basic example:

import org.openjdk.jmh.annotations.*;

@State(Scope.Thread)
public class MyBenchmark {
    @Benchmark
    public void testMethod() {
        // Your code to benchmark
    }
}

How do I interpret the results from a JMH benchmark?

You can interpret the results by looking at metrics like throughput, average time, and error rates to understand performance.
