@ vaibhav when we are sure that we dont need a particular object we can call gc On Mon, Aug 1, 2011 at 1:46 AM, Deepthi Srinivasan deeps1...@gmail.comwrote: Garbage collector'll never run according to our whims and fancies :P It'll run only when it wants (mostly when it senses that memory is going down). We can issue a request using system.gc but we cannot MAKE it run...

Re: [algogeeks] HOW GARBAGE COLLECTOR WORKS IN JAVA
Garbage collection is totally JVM dependent... Some JVMs may use a mark and sweep algorithm. The first thing u should understand abt Java's garbage collection is totally unpredicatble. You cant really predict when garbage collection is done. If and when the JVM decides that garbage coll should be run, it checks all objects, and those objects which have no references to it will be deleted from the heap memory. System.gc() makes a request to the JVM to run the garbage collection mechanism. But its a bad practice to call it, because you cant really be sure that JVM will not choose to ignore it. Moreover you can safely ignore it cos the JVM, most probably is smarter than you, and knows when to run the garbage collection mechanism on its own...
