What is tight coupling and loose coupling?

Tight Coupling means one class is dependent on another class. Loose Coupling means one class is dependent on interface rather than class. In tight coupling, there are hard-coded dependency declared in methods. In loose coupling, we must pass dependency externally at runtime instead of hard-coded.

What is cohesion in oops?

Cohesion is the Object Oriented principle most closely associated with making sure that a class is designed with a single, well-focused purpose. The advantages of high cohesion is that such classes are much easier to maintain (and less frequently changed) than classes with low cohesion.

What is meant by loose coupling?

Loose coupling refers to the connection between components of a system or network, such as software applications or hardware. It’s an approach in which components (or elements), although connected, aren’t dependent on one another.

What are the benefits of loose coupling?

The primary benefit of Loose Coupling is that resources are decoupled from the interface to allow for greater amounts of interoperable, extensible APIs and resource schemas. Not all services require this, however. There are some cases where one has a single resource and a single interface of a single type.

What is meant by tight coupling?

The tightly coupled object is an object that needs to know about other objects and is usually highly dependent on each other’s interfaces. Changing one object in a tightly coupled application often requires changes to a number of other objects.

Why is tight coupling bad?

In general, Tight Coupling is bad in but most of the time, because it reduces flexibility and re-usability of code, it makes changes much more difficult, it impedes test ability etc. loose coupling is a better choice because A loosely coupled will help you when your application need to change or grow.

Is high cohesion bad?

High Cohesion and low coupling give us better designed code that is easier to maintain. High cohesion: Elements within one class/module should functionally belong together and do one particular thing. Loose coupling: Among different classes/modules should be minimal dependency.
