| | Class inheritance: colon + base class |
| |
| | Private class-level variables: inherited but not accessible |
| |
| | Value: keyword for implicit input name of the set method in object classes |
| |
| | Protected class-level variables: available to classes in the same namespace |
| |
| | Protected internal: available to derived classes, and classes within the same Assembly, and the base class |
| |
| | Default constructor: disappears when any constructor is written |
| |
| | System.Object: top .NET class that everything is derived from |
| |
| | Method overriding: changing the method behavior for a derived class |
| |
| | Method overloading: using the same method name again in the same class but with different number, type and order of
parameters |
| |
| | Virtual method: can be over-ridden but cannot change method signature |
| |
| | Method signature: its name and the number and type of its parameters, where the last parameter may comprise of an array
of values |
| |
| | Sealed class (in Java, final class): cannot be inherited |
| |
| | Sealed method: method cannot be inherited but class can when not sealed |
| |
| | Abstract class (in C++, pure virtual method): blueprint for a class without any implementation and thus cannot be
instantiated |
| |
| | Abstract class methods: not all must be abstract, some can be concrete |
| |
| | Abstract class required when at least one of the methods in the class is abstract |
| |
| | Abstract method: require non-abstract derived classes to provide their own implementation of this method |
| |
| | Interface class? an abstract class with public abstract methods all of which must be implemented in the inherited classes |
| |
| | Interface class methods: all must be abstract and public and thus accessibility modifiers not needed |
| |
| | Multiple interfaces: can be inherited |
| |
| | Namespace class: classes are declared inside a namespace |
