More On The Memory Leak In Java 
A memory leak can
be caused due to poor programming like keeping the references
null for several objects when you are working with the
program. If you write the java program in such a manner
that it needs to run continuously on a server there
is a possibility of you facing a memory leak.
This type of memory leak can also be very risky and
even if the program is small it has the capacity to
exceed the memory limits and result into a memory
leak. This occurs as in many cases the Java
program retains the memory for many used objects and
this is the reason why there is a leak.
When you are working on Java you will often find that
an error message arises with an out of memory indication.
The cause of such a memory leak can
be difficult to ascertain however if we are careful
we do have the ability to control the occurrence of
such a memory leak on our computer.
There are some common places in the computer where we
can find the cause of the memory leak and you have the
option to check into the vectors and the hashmaps as
these are the primary areas where the memory
leak may be caused. Another cause of a leak
can be where we tend to register the event listener
to one class and subsequently fail to unregister it
when it is not required anymore. In order to fix a memory
leak you can use a debugging tool like the
JProbe, the Optimizeit, Win32Java Heap and a load of
other similar debugging applications.
Thus in this manner you will be able to fix a memory
leak that occurs in Java. You can do it yourself
with the aid of the debugging tools that have been listed
above.
