A new file or not

[Gary Ba]

Hi Yall,
I have a question about the style of programming.

If I have to create a small class/interface, will it be a good idea to create a new file or just write it along the file which will use it. I always thought it will be best to always separate classes and interface in each java file.

I am interested in others opinion or experience.

Holler,
Garry

When you say interface... you don't mean a real interface (as in something a class implements), right?

You mean like a user interface?

I like this format myself

Main method starts the user interface:

// inside main
UserInterface interface = new UserInterface();   
interface.start(); 

and then create a HAS a relationship so the UI can interact with the algorithms you need.

Dunno if it's "javaranch correct" but it's what I've done and it seems pretty clean.

Here is what I mean....

 

interface OtherClass implements TheOtherClass
{
    method()..
    others..
}

class ClassName
{
    method()..
    others..
}

My question is....
Is it in good practice to separate the OtherClass and ClassName in two files or one file?

[Janeice DelVecchio]

You can do either, but I make 2 separate files incase something else ever implements the same thing.

Again.... not sure of the JR right way.....

I think it's usually best to maintain 2 files unless one is an inner class.
