As you know the Garbage Collection shouldn’t happen too soon or too late, because in both cases the performance of the system gets affected. A delay in GC cycles results in memory leakage, whereas too many GC cycles reduce system performance and increase CPU usage. Along with this we also need to understand how much … Read more
When it comes to the memory management of a software application, garbage collection is crucial. Actually, the memory of unused or unreferenced objects is recovered by a Java program called Garbage Collector. It means that, like other Java codes, the GC executes when a certain condition, such as memory fullness, is met. GC affects the … Read more
Before discussing the type of garbage collector, it is important to understand some basic terms related to it. Type of Garbage Collector: 1. Serial GC: Serial GC is designed for single-threaded environments. It uses just a single thread for garbage collection. As a result, this GC implementation freezes all application threads when it runs. This leads … Read more
A Garbage Collector is a Java program which tracked the referenced (live) objects and allowed them to keep in the heap memory whereas the memory of the unreferenced (dead) objects is reclaimed and reused for future object allocation. To understand it more practically we have to take some pictorial examples of JVM object creation and management cycle. Let’s … Read more
What is Memory Heap? A heap is a portion of memory which is used for dynamic allocation. The blocks of the memory in the heap are frequently allocated and freed based on the status of the object. The allocation and release of memory take place in an arbitrary order and hence the unreferenced or dead … Read more
A Garbage Collector is a Java program which tracked the referenced (live) objects and allowed them to keep in the heap memory whereas the memory of the unreferenced (dead) objects is reclaimed and reused for future object allocation. This method of reclaiming unused memory is known as Garbage Collection. In Garbage collection, neither the explicit deletion of … Read more
