What is the definition of “interface” in object oriented programming
...ns of the non-private methods. Because of how C++ compiles, you get header files where you could have the "interface" of the class without actual implementation. You could also mimic Java interfaces with abstract classes with pure virtual functions, etc.
An interface is most certainly not a bluepri...

...ecommended in the specification). The JVM specification is about the class file format and not the Java Source code. - Indeed the order does not matter but if you follow a recommendation your code will be more readable to others.
