We can also resort to reference objects in Java that come built-in with thejava.lang.refpackage to deal with memory leaks. Using thejava.lang.refpackage, instead of directly referencing objects, we use special references to objects that allow them to be easily garbage collected. Reference queue...
we can have very fast access.Terracottahas been pushing theBig Memoryconcept in the Java world for a few years now. Redis and memcached are good examples of in-RAM quick
Garbage First Collector doesn’t work like other collectors and there is no concept of Young and Old generation space. It divides the heap space into multiple equal-sized heap regions. When a garbage collection is invoked, it first collects the region with lesser live data, hence “Garbage Fir...
As mentioned above, the concept of heap space exists both in Linux process memory layout and JVM memory layout but differs immensely. Therefore, it is easy for us to confuse one with the other. The Java heap is smaller in scope than the heap of a Linux process. It is a segment of log...

To make the optimal use of the memory that is provided by the operating system to the Java program, you may need to understand the concept of Java heap and Native heap. The operating system allots a part of memory to the Java application. That part is divided into two parts: Java heap...

it is essential to have a good understanding of how Java manages memory using the concept of a virtual memory map. In this article, we will explore the Java virtual memory map, its components, and how it is used in practice. We will also provide code examples to illustrate these concepts...
monadsThis paper describes how the concept of monads was used to implement CMTJava, a Domains Specific Language (DSL) for composable memory transactions in Java. Furthermore, the paper also proposes DCMTJava, a DSL that supports transactions using distributed objects....
JVM is the abbreviation of Java Virtual Machine, which is a kind of simulated virtual computer, which is realized by simulating computing functions in different computer environments. After the introduction of the Java virtual machine, the Java language does not need to be recompiled when it runs...
