Question
How to clear Memory using JAVA?
Hi,
I have been facing the problem of OutOfMemoryError. I used Hashtables in the program, but they were never been cleared from the memory. Can somebody teach me how to clear the Hashtables from the memory?
Currently I used Hashtable.put to add an object to the hashtable. I noticed there is a method remove to remove the object. Can I use this? If I use the remove method, will it be cleared from the memory?
Thanks,
rospcc

>>"I noticed there is a method remove to remove the object"
Nope, this will only remove the object from the HashTable.
Okay, memory is cleared by the Garbage Collector which is present in every JVM. Normally, we should not interfere this.
You can add the memory for JVM of your application and make sure you set your HashTable to null once it is no longer used.
