Download the whole handbook as a 28-page PDF or e-book java.lang.OutOfMemoryError: https://plumbr.eu/outofmemoryerror/java-heap-space Java heap space Java applications are only allowed to use a limited amount of memory. This limit is specified during application startup. To make things more complex, Java memory is separated into two different regions. These regions are called Heap space and Permgen (for Permanent Generation): The size of those regions is set during the Java Virtual Machine (JVM) launch and can be customized by specifying JVM parameters -Xmx and -XX:MaxPermSize. If you do not explicitly set the sizes, platform-specific defaults will be used. The java.lang.OutOfMemoryError: Java heap space error will be triggered when the application attempts to add more data into the heap space area, but there is not enough room for it. Note that there might be plenty of physical memory available, but the java.lang.OutOfMemoryError: Java heap space error is thrown whenever the JVM reaches the heap size limit. What is causing it?There most common reason for the java.lang.OutOfMemoryError: Java heap space error is simple - you try to fit an XXL application into an S-sized Java heap space. That is - the application just requires more Ja
in Java Everyone in java development faces java.lang.OutOfMemoryError now and then, OutOfMemoryError in Java is one problem which is more due http://javarevisited.blogspot.com/2011/09/javalangoutofmemoryerror-permgen-space.html to system's limitation (memory) rather than due to programming mistakes in most cases though in certain cases you could have a memory leak which causing OutOfMemoryError. I have found that even though java.lang.OutOfMemoryError is quite common basic knowledge of its cause and solution is largely unknown among junior developers. Beginners books like Head error java First Java doesn't teach you much about how to deal with this kind of error. You need real experience dealing with production systems, handling a large number of user sessions to troubleshoot and fix performance issues like running out of memory. If you want to be good at troubleshooting and performance analysis, you out of memory need to learn some books on Java performance and profiling e.g. Java Performance The Definitive Guide By Scott Oaks or the Java Performance by Binu John. They are an excellent resource for senior Java developers and also teaches you tools and process to deal with an error like java.lang.OutOfMemoryError. In this article, we will explore what is java.lang.OutOfMemoryError; Why OutOfMemoryError comes in Java application, different type of OutOfMemoryError and How to fix OutOfMemoryError in Java. This article is purely meant to provide basic knowledge of java.lang.OutMemoryError and won't discuss profiling in detail. For profiling read the books I have mentioned before. What is java.lang.OutOfMemoryError in Java OutOfMemoryError in Java is a subclass of java.lang.VirtualMachineError and JVM throws java.lang.OutOfMemoryError when it ran out of memory in the heap. OutOfMemoryError in Java can come anytime in heap mostly while you try to create an object and there is not enough space on the heap to allocate that obj
