SomeClass classvar = new SomeClass(); --> Object classvar = new SomeClass(); --> Object 2 So what I understand about JAVA is that , in the first line, classvar object of SomeClass is created. In the next line, there is another object created of classvar.
My Question - What will be changed here? Will the reference of classvar object be updated due to second line ORR the object created in line 1 will be garbage collected?
EDIT: adding code tags
I think you might be asking about:
SomeClass classvar = new SomeClass();// --> Object 1 classvar = new SomeClass();// --> Object 2 And if that is the case, then the first SomeClass object that was created will lose its reference and will eventually be garbage collected (this means that the object is destroyed to free up memory).
And the classvar variable will now reference the second SomeClass object that was created.
That is a compile error you cannot have two variables of the same name in java
if you meant
SomeClass classvar = new SomeClass(); --> Object 1 classvar = new SomeClass(); --> Object 2 then the first objects reference the the first Object will get overwritten with the new reference. And the next time the gc runs it will be deleted.
SomeClass classvar = new SomeClass(); classvar = new SomeClass();?
