There are a few ways to check your code to see if it has suffered a memory leak. Java memory leaks occur when there is an overlap of unreferenced objects that appear to still be in use. The garbage collector will not clean objects that appear to be referenced, or in use. The job of the garbage collector is to find and identify unreferenced objects and remove them. Referenced objects still have active connections to the Java application, while unreferenced objects do not. In memory, objects can have two states, unreferenced and referenced. This stops the garbage collector from clearing the memory, causing the memory to eventually max out and crash. Java memory leaks are caused when objects that are unreferenced get categorized as referenced. Sometimes java memory leak crashes don’t output an error, but oftentimes the error will terminate with a. If left unchecked, these objects will continue to consume system memory and eventually cause a crash. In Java and most other programming languages, a garbage collector is tasked with removing objects that are no longer being referenced by the application. Simply put, Java memory leakage is when objects are no longer being used by the application but are active inside the working memory. In this article, we’ll dive into exactly what causes memory leaks in Java, and suggest some of the best tools you can use to stop memory leaks before they ever happen. Have you experienced freezing or sudden crashes in your Java application? Chances are you may have experienced Java memory leakage.
