Properties should be understood as certain characteristics of the functionality and state of an object. The inheritance relationship between types is a special case relationship: descendants must be special cases of the ancestor. The principle tightens the requirements for future generations. It is well known that the negation of the consequent leads to the negation of the antecent so this principle can be restat as follows: If you can find a property that satisfies all objects of type and does not satisfy at least one object of type then types should not follow types. A violation of the principle may result in a polymorphism violation when a descendant object cannot replace an ancestor object in a specific context (program). For example a violation of the principle can be call like this.

There are two classes

If we inherit the first class from the second class (square is a special case of rectangle) then we will be violat if the rectangle has functionality to change width Oman Telegram Number Data but not height. Interface Isolation Principle ( ) Clients should not rely on methods they do not use. Creating small, dicat interfaces should be a priority when designing interfaces. If this principle is violat the code will rely on functionality it does not use which will make the code difficult to maintain and a potential source of bugs. Dependency Inversion Principle ( ) Dependencies in source code should be direct to abstractions rather than concrete implementations.

This is a principle that allows you

To ruce dependencies between components. The implementation of Germany Email List the principle can be illustrat through an example. If a class depends on a class then it depends on the specific implementation. You can replace this dependency with two dependencies on an abstraction in the form of an interface to create flexible systems in which some components can be replac or chang without affecting other components. Why is this important? The principles are interrelat and provide the foundation for creating high-quality and maintainable software systems.
