GC doubt

[ramya ray]

Hi, please guide what can be correct option..

class A{

public static void main(String args[]){
Object o = new Object(); //line 1
method(o); //not defined
o = null; // line 2
}

}

when will the object created at line 1 will be eligible for GC.
1. at line 2
2. it is not known to be sure.

I think it will be option 2.
Please help
Thanks !

"method" might save a reference to "o" so you can never be sure
