Garbage Collection

[Akash Bhatt]

public class XYZ{
ABC obj=new ABC();
mth1{
System.out.println(obj);
}

}
public class C{
public static void main{
XYZ obj1= new XYZ();
obj1.mth1();
}
}

in Class C when main method ends the object for XYZ is eligible for collection by the GC. But happens to the reference 'obj' created in XYZ..??? Is IT too eligible for collection..??

If main threads ends up then all objects are eligible for Garbage Collection.

It's quite obvious.

Pls correct me If I am wrong.

Yes, the object of type ABC referenced by obj is eligible for garbage collection. You effectively have two linked objects with no active thread referencing either of them. Imagine a red kite tied to a blue kite. If you are holding the string to the blue kite and you let go, both kites will be blown away.
