What is the purpose of garbage collection in Java, and when is it used?

The purpose of garbage collection is to identify and discard objects that are no longer needed by a program so that their resources can be reclaimed and reused. A Java object is subject to garbage collection when it becomes unreachable to the program in which it is used. Garbage collection is also called automatic memory management as JVM automatically removes the unused variables/objects value is null

Define Garbage collector.

Garbage Collection is a process that many Operating Systems and some applications, especially services perform.The purpose of Garbage Collection is to recover or reorganise system resources such as available blocks of RAM to prevent failure due to resource starvation. Garbage collection is an automatic memory management feature in many modern programming languages, such as Java and languages in the .NET

Does Java have destructors?

instead of destructor in j...ava it has its own mechanism for memory management an that is called garbage collection. garbage collector calls the finalize method which is defined in the object class is invoked before the system garbage collects the object.While core Java does not have destrcutors, may classes in the Eclipse SWT API do in fact have destructors. You must explicitly call component

Are C destructors the same as C destructors?

method is called by the garbage collector when it determines that an object is no longer referenced, before it frees the memory associated with the object. So far this sounds like a C destructor. The difference is that the garbage collector makes no guarantees about when this procedure happens. Indeed, the algorithm employed by the CLR garbage collector means that it may be a long time after

Are C destructors the same as C destructors?

No, The C destructor syntax with the familiar character is just syntactic sugar for an override of the System.Object Finalize method. This Finalize method is called by the garbage collector when it determines that an object is no longer referenced, before it frees the memory associated with the object. So far this sounds like a C destructor. The difference is that the garbage collector makes

what is memory leak in java?

the JVM to perform garbage collection when desired. This capability turned out to be very useful when trying to see if a given instance of a class would be garbage collected when it was no longer needed, you were promised that Garbage Collection GC in Java will relieve you from the mundane duties of allocating, tracking, and freeing the heap memory. Indeed, the promise has been delivered, so
