Garbage Collection in Java (JVM)

Garbage Collection in Java (JVM)

Garbage Collection in Java automatically allocates and deallocates memory, so that developers don’t need to write an explicit program to do memory management, which is one of the main advantages of Java programming. Whenever a Java program runs on the JVM, the objects are created on the heap and are a portion of memory that is dedicated to the program. Eventually, some objects will no longer be needed. The garbage collector finds these unused objects and deletes them to free up memory.

Garbage Collection Process in Java

Garbage Collection in Java automatically allocates and deallocates memory, so that developers don’t need to write an explicit program to do memory management, which is one of the main advantages of Java programming.

Whenever a Java program runs on the JVM, the objects are created on the heap and are a portion of memory that is dedicated to the program. Eventually, some objects will no longer be needed. The garbage collector finds these unused objects and deletes them to free up memory.

The** garbage collector** will look 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 object, or unreferenced object, is no longer referenced by any part of your program. So the memory which is used by an unreferenced object can be reclaimed by performing a Garbage Collection.

Deallocation of memory can be described in 3 basic processes:

  1. Marking
  2. Normal Deletion
  3. Deletion with Compacting
