Why does Java compiler decide whether you can call a method based on the “reference” type and not on actual “object” type?
I was just wondering why does Java compiler decide whether you can call a method based on the “reference” type and not on actual “object” type? To explain I would like to quote an example:

Do I have to release source code because I’m using JavaFX?
I’m using JavaFX for gui of my app. Its license is GPL+Linking Exception. GPL requires me to release my source code. But what’s the linking exception?? (I’m just using it as a library. Not modifying or using its source code.)

How to make a method synchronized across all instances of a class
Today I was asked this interview question and could not answer.
If you have two instances of a Person class which has a setAddress method that is synchronized. Now if it was only one object and multiple threads were accessing it, the synchronized
will make sure that only one method can access it at a time.
Why do different java collections have different default capacity?
Looking at different collection constructors the question comes to mind. Why does ArrayList()
construct an empty list with an initial capacity of ten and ArrayDeque()
constructs an empty array deque with an initial capacity sufficient to hold 16 elements.
