It's better to open and close a file straight away after you're done with reading/writing. Don't keep it open as you cannot tightly control what happens to your view (e.g. other processes can come in front, OS can decide to kill your process, etc).
Where should the close() function be called for this RandomAccessFile object

Question
I have a class called GraphView that extends View and I do some calculations in side this class
The object of this class represents a custom Graph that I display on the screen. This is created in the MainActivity file
I need to save the value of an array inside the extended View class so I want to create a RandomAccessFile object inside the class, I will probably initialize this object inside the constructor of GraphView, but where do I specify the close() function?
The graph will stay on screen as long as the program runs so I am not sure where the close() function should be, as there does not seem to be a destructor in Java.
