However, when you don’t need it anymore, instead of “freeing” it from the memory, you move on. Think of ths example: imagine you had to create an object that you needed. What it really is, is memory that has not been released back to the pool. If you have written Java applications before you probably came across this widely-spread issue. In case you don’t, feel free to read this article and this one as well. To understand memory leak, it would be a good idea if you have the fundamental knowledge about memory. Let’s try a real use case for using JProfiler (or profiling in general) – Memory Leak detection What is Memory Leak? Note that the image below shows a running application.Īs you can see from the image above, it shows different components that are directly related with performance, memory and can easily help you optimize your program. With all this information provided, we can diagnose our application’s behaviour and change it if we need to. It has relatively easy-to-use interface that helps inspecting the system performance, memory usage, memory leaks (if any) and thread profiling. When it comes to profiling tools, JProfiler is the best choice for many developers. You can use the IDE to profile theses types of Java applications: by monitoring the JVM (Java Virtual Machine). Profiling examines an application and tries to locate memory or performance issues that are associated with a Java application.What it allows you to do is obtaining data about the performance, method timing, object allocation, etc. If you are not very familiar with Unit Testing, I suggest following this tutorial on the topic.
And even if it is, you can use unit testing to determine whether another implementation would give better result in terms of memory and performance.

Its purpose is to confirm the fact that every piece of the software behaves as expected. Unit tests are a method of software testing in which small components of a Java application are being tested.
