In Java, a Has-A relationship essentially implies that an example of one class has a reference to an occasion of another class or another occurrence of a similar class.
Sep 12, 2024 · Loose coupled systems are ideal for tasking that will hardly involve much interaction between the processors while in the case of tasks that will need much of the processors’ interacting then a tightly coupled system is desirable.
5 days ago · I came across the concept of loose coupling, and I understand that Spring promotes defining behavior in interfaces. However, I am wondering why it's necessary to define behavior in an interface instead of directly extending the implementation in a class?
4 days ago · Coupling in Java. Coupling refers to the relationship between two classes. It indicates the knowledge one object or class has of another. That means that if one class changes its properties or behaviour, it will affect the dependent changes in the other class.
Sep 16, 2024 · This adds unnecessary complexity and coupling. Example: Let’s say we have an interface Worker with both work() and eat() methods. Robots, however, don’t eat, so implementing the Worker interface forces them to have an unnecessary method. Violating ISP (Bad Design):
Sep 1, 2024 · Definition of OOP Concepts in Java. The main ideas behind Java’s Object-Oriented Programming, OOP concepts include abstraction, encapsulation, inheritance and polymorphism. Basically, Java OOP concepts let us create working methods and variables, then re-use all or part of them without compromising security.
