When to use System.runFinalization() and System.gc() ??

[kmthien]

Hi,

When should I use System.runFinalization() and System.gc() in a Java program ? Thanks in advance !!

You shouldn't have to for most applications. The Java VM does a pretty good job cleaning up after itself automatically.

Then why Java still offering this function ?? Thanks a lot for your valuable comment !!!!

So .... do u like these functions ?? Tell me....

 

[kmthien]

No, you should probably leave the Java virtual machine to its own garbage collection devices rather than force a full garbage collection cycle. Unless you are writing something that is allocating extremely large amounts of memory, there is no need to force a garbage collection.
