DEAR NEW mEMBER...
Salam,
its known that JAVA had elimenated pointers in
C language, and introduced a new way of defining
variables- by creating OBJECTS

an object is a pool of memory that is referenced
by variable name ( passed by reference).

suppose you defined a String object :

String s = new String("Hi");

this means that s points to Hi,
now notice:

s = new String ("welcome");

what happens then??
s variable will leave pointing to "Hi", and
points to a new memory pool containing "welcome"

"Hi" will remain in memory without being freed,

so Garbage collection 'collect' all variables
that lost thier reference and free thiert space
and resources again.

Grabage Collection is one reason why Java runs
slow.
