It makes java memory efficient because garbage collector removes the unreferenced objects from heap memory.
It is automatically done by the garbage collector(a part of JVM) so we don't need to make extra efforts.

Java Memory Management, with its built-in garbage collection, is one of the language's finest achievements. It allows developers to create new objects without worrying explicitly about memory allocation and deallocation, because the garbage collector automatically reclaims memory for reuse.

The garbage collector is a program which runs on the Java Virtual Machine which gets rid of objects which are not being used by a Java application anymore. It is a form of automatic memory management.

It makes java memory efficient because garbage collector removes the unreferenced objects from heap memory. ... The finalize() method is invoked each time before the object is garbage collected. ... The gc() method is used to invoke the garbage collector to perform cleanup processing.

Garbage Collection is an automatic memory management feature. The process of destroying unreferenced objects is called Garbage Collection. Once object is unreferenced it is considered as unused object, hence JVM automatically destroys that object.

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. So, java provides better memory management.

All objects are allocated on the heap area managed by the JVM. ... As long as an object is being referenced, the JVM considers it alive. Once an object is no longer referenced and therefore is not reachable by the application code, the garbage collector removes it and reclaims the unused memory

[samuelsam]

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) from the memory.

An excerpt of chapter 9, Garbage Collection, of Bill Venners' book Inside the Java Virtual Machine.

[rekhar]

Garbage Collection” as the name suggests is used to remove the objects that are no longer needed by the Java application. The Java Garbage Collector will identify those objects and remove those from the memory thereby freeing the memory for the new objects.
