Setting References to Null

Posted by Akin Kaldiroglu on 05 Apr 1999, 8:06 AM

I am using JDK 2.0 and when I set an object to null, system does automatically
call GC and run finalize() method on that object. It does this after about 1 minute.
But as you know this behavior might be particular to the GC mechanism of JVM
in JDK 1.2.
