Java Interface Simple Example

@pr0master
Interface make it more formal for classes. if a class implements some interface it commits to have certain behaviors (methods) that it promises to provide. and sure you can still make two methods without using any interface. it just matters with a big project with tons of classes.

>.< i still dont know what it does or what you would use it for

[pianoman]

if all it does is say hello world cant you just so something like Class.Function();
to call the function instead of all that

I find it hard to understand. Why use a interface? You could make two methods without a interface.

no need to have interface for that program...
