can any one explain the solution for this program
Given:
1. public class GC {
2. private Object o;
3. private void doSomethingElse(Object obj) { o = obj; }
4. public void doSomething() {
5. Object o = new Object();
6. doSomethingElse(o);
7. o = new Object();
8. doSomethingElse(null);
9. o = null;
10. }
11. }
When the doSomething method is called, after which line does the Object created in line 5
become available for garbage collection?

Re: can any one explain the solution for this program
You will know if an object is eligible for garbage collector if it becomes UNREACHABLE, and this happens when you don't have any reference variable pointing to it. With this knowledge, you will be able to answer that.
