The Fission Theory: This theory proposes that the Moon was once part of the Earth and somehow separated from the Earth early in the history of the solar system.
This provides modular approach to programming. Classes. A class is a concept used in object oriented programming languages such as C++, PHP, and JAVA etc. Apart from holding data, a class is also used to hold functions. An object is an instant of a class. In case of variables, the type is the class whereas the variable is the object.
For example, on Int means âless than or equal toâ , but it might mean something else in another class. :: in an expression is probably the method of the class List but it can also refer to the object of the same name (and in a pattern it definitely does).any symbols are simply methods of a class, a trait, or an object. For instance, if you do. Youâll find the method ++ right on the ScalaDoc for List. However, thereâs one convention that you must be aware when searching for methods. Methods ending in colon (:) bind to the right instead of the left.
