   Feb 14, 2022 · Java garbage collection is an automatic process. Automatic garbage collection is the process of looking at heap memory, identifying which objects are in use and which are not, and deleting the unused objects. An in-use object, or a referenced object, means that some part of your program still maintains a pointer to that object. An unused or ...

   Java Garbage Collection. In java, garbage means unreferenced objects. Garbage Collection is process of reclaiming the runtime unused memory automatically. In other words, it is a way to destroy the unused objects. To do so, we were using free () function in C language and delete () in C++. But, in java it is performed automatically.

   What is garbage collector in Java?

   • But in Java, the programmer need not care for all those objects which are no longer in use. Garbage collector destroys these objects. The main objective of Garbage Collector is to free heap memory by destroying unreachable objects. The garbage collector is the best example of the Daemon thread as it is always running in the background.

   What is garbage collection in C++?

   • Garbage Collection is the process of reclaiming the runtime unused memory by destroying the unused objects. In languages like C and C++, the programmer is responsible for both the creation and destruction of objects. Sometimes, the programmer may forget to destroy useless objects, and the memory allocated to them is not released.

   Why is garbage collection important in Java?

   • It also makes Java memory-efficient because the garbage collector removes the unreferenced objects from heap memory. This frees the heap memory to accommodate new objects. While some programmers argue in favour of manual memory management over garbage collection, garbage collection is now a standard component of many popular programming languages.

   Where does garbage collection occur in Java?

   • The garbage collection implementation lives in the JVM. Two types of garbage collection activity usually happen in Java. These are: Minor or incremental Garbage Collection: It is said to have occurred when unreachable objects in the young generation heap memory are removed.

   How does generational garbage collection work in Java?

   • Since Java uses generational garbage collection, the more garbage collection events an object survives, the further it gets promoted in the heap. It starts in the young generation and eventually ends up in the tenured generation if it survives long enough.

   What events trigger garbage collection in Java?

   • There are several events that can trigger garbage collection in Java: Heap space allocation: When the JVM needs to allocate memory for a new object, and there is not enough space in the heap, it triggers garbage collection to reclaim unused memory or store them in the survivor space.

   Sep 3, 2021 · Garbage collection is a key feature for developers who build and compile Java programs on a Java Virtual Machine, or JVM. Java objects are created on the heap, which is a section of memory dedicated to a program. When objects are no longer needed, the garbage collector finds and tracks these unused objects and deletes them to free up space.
