|
14 |
+1. A generic, high-level unit. For example, a class contains two functions that contain duplicate code, which should not happen according to the DRY principle. The duplication can be resolved by moving the duplicate code to a common function (the "Abstraction" of that code) and calling the function where the code was previously located. The duplicate code was "abstracted". |

|Aware/Unaware|(% style="text-align:justify" %)The class A contains a source code reference of the class B and therefore is aware of the class B. If you were to read only the source code of class A, you would know that there must be a class B. If there was no such reference, class A would be unaware of class B. |

|Data Structure|(% style="text-align:justify" %)A very simple type of class that contains only data and no logic. For example, a class that has only public fields but no methods. Another form is a class with private fields and simple corresponding getters and setters. |

|Dependency|(% style="text-align:justify" %)In the context of classes, a dependency is a field that must be initialized with an instance of another class in order for an object of that class to function properly. Often, the initialization is realized via Dependency Injection. |
