Cohesion in Java. In object oriented design, cohesion refers all about how a single class is designed. Cohesion is the Object Oriented principle most closely associated with making sure that a class is designed with a single, well-focused purpose. The more focused a class is, the cohesiveness of that class is more.

Accordingly, what is cohesion explain with example?

Cohesion means sticking together. If your group of friends heads to the lunchroom as a team and sits all together, you're demonstrating strong cohesion. Cohesion is a word that comes to us through physics, where cohesion describes particles that are the same and tend to stick together — water molecules, for example.

Subsequently, question is, what does highly cohesive mean? High cohesion is when you have a class that does a well defined job. Low cohesion is when a class does a lot of jobs that don't have much in common. To create a high cohesive solution, you would have to create a class Window and a class Sum.

In this regard, what are the pros of a high cohesive class?

Advantages of high cohesion (or "strong cohesion") are:

  • Reduced module complexity (they are simpler, having fewer operations).
  • Increased system maintainability, because logical changes in the domain affect fewer modules, and because changes in one module require fewer changes in other modules.

What is loose coupling and high cohesion in Java?

cohesion: degree of well defined definite purpose of a class. low cohesion means a class has varied purpose of existence. high cohesion means a well defined definite purpose of existence. coupling is a degree in which one class knows about the other class.

What does loosely coupled mean?

Subareas include the coupling of classes, interfaces, data, and services. Loose coupling is the opposite of tight coupling.
