Implicit object creation

[RHC]

I have a question regarding garbage collection. Assume the following

public class Myclass
{
public Myclass()
{}
public int getTheNumberOne()
{ return 1;}

}

Now suppose in some other class, say a servlet or something I have the following..

int first = new Myclass().getTheNumberOne();

when / how is this new Object of type Myclass garbage collected???

TIA

RHC

The how is the same as any other garbage collection.

The when is entirely at the discretion of the JVM based on numerous
factors. But it's eligible for collection immediately after the
execution of that line since you're not keeping a reference to the
created object.

That's the good thing about it - you don't need to know - its taken care of
by the jvm

Agreed. But I think it's worth adding that most GC implementations are
specifically optimised to handle short-lived garbage (such as the temporary
object in the OP's post) efficiently.
