Like in C++, we can deallocate memory using destuctor, but in Java this mechanism of deallocation memory of object is handled by Garbage Collector, it deallocate memory of the object which no longer needed.

Garbage collection (GC) is a form of automatic memory management. The garbage collector, or just collector, attempts to reclaim garbage, or memory used by objects that will never be accessed or mutated again by the application.

Like in c and c++ we have some mechanism to create the object and some mechnaishm to distroy the object .but in java  we have mechanism to create the object but we dont have any  mechanism to distroy the object ..so some data can be unused that unused data is garable but as a doveloper we dont have authority to remove the data tht is done by gc() according to JVM instruction.we cant force to gc ().In following cases object is eligble for garbage collection
1.Hello h=new Hello()
Hello h1=new Hello()
h=h1
then h is eligble for gc
2.Hello h1=new Hello()
Hello h1=null
then create object will be eligble for gc
3 when objecdt is out of scope then object will eligble for gc
