Understanding Heap Memory in Java Applications
Let us begin with a pretty simple question. Does every Java Developer understand how memory works in Java? One goal of a Java Developer is to make sure their application has some of the best performance it can get from fine-tuning their Java software applications. Java Memory Management takes some time to learn and understand for everyone who uses Java. The goal of this article is to help people understand how to gain these skills.
The whole idea is to allow the process of allocating new objects and removing unused objects – better known as Garbage Collection (GC) in the Java programming language – properly. By default, Java manages memory automatically pretty well. This is due to the garbage collector in the background to clean up unused or unreferenced objects to free up some percentage of memory.
Without the proper experience and knowledge of how the Java Virtual Machine (JVM), Garbage Collector, and how Java uses memory, a lot of the Java Developers will not find and fix the bottlenecks when we execute Java code and test for performance.
