Is it possible to change the priority of garbage Collector thread?

Question

Java garbage collector runs with priority 1, due to which it is not guaranteed that System.gc() will actually execute if called.

Is there any way to change its prio

Answer 1

When a thread is created it inherits the priority of the thread that created it. The priority of a thread can be adjusted by using

public final void setPriority(int newPriority)

The problem is a thread doesn't "run" the garbage collector. The garbage collector is run by the VM (when Java wants or is in "good mood .. :)" ).

EDIT: The GC is not a thread but a method of the Runtime thread. You can change the priority of the Runtime thread but this will have no effect on the GC. The thread that calls the GC is a thread of the VM and is out side the scope of the API so you can't change its priority.

So, I don't really think you can set its priority.
