Coupling In order to create an effective application that is easy to develop, easy to maintain and easy to update, we need to know the concept of coupling and cohesion. Content Coupling: In a content coupling, one module can modify the data of another module or control flow is passed from one module to the other module. Coupling refers to the degree of direct knowledge that one element has of another. Tight coupling creates situations where modifying the code of one object also requires changing the code of other objects (also known as a ripple effect). Our relations diagram then looks as follows: As you can see the objects are all pretty well interrelated. If the Pac-Man object were to track when it ate a power pellet and then initiate the change state of each ghost, the system would be tightly coupled.

Coupling refers to the usage of an object by another object. Another class would be responsible for keeping track of the bullet's position as well as what happens when a bullet hits an asteroid. Tight coupling - When an object creates the object to be used, then it is a tight coupling situation. Recall that the objects are a ship, an asteroid, a flying saucer, and a bullet. Greedy quantifiers Java Regular expressions in java. This made the code fairly clean and easily changeable. This created bloated code that was hard to change and difficult to maintain. Java Programming Java8 Object Oriented Programming. If the ship were to create a bullet object, keep track of its position, and then modify the asteroid when the bullet hits, our system would be very tightly coupled. As the main object creates the object itself, this object can not be changed from outside world easily marked it as tightly coupled objects.

Modularization: Modularization is the process of dividing a software system into multiple independent modules where each module works independently. Coupling is the principle of reducing how objects directly affect the states and behaviors of other objects.

Describes the functionality of the system. developer. Loose coupling - When an object gets the object to be used from the outside, then it is a loose coupling situation. When a class uses another class, or communicates with it, it's said to 'depend' on that other class, and so these classes are 'coupled'. It can also be termed as collaboration. It basically refers to the extent of knowledge one class knows about the other class. Writing code in comment? Note: Although this tutorial is written using Java, you should be able to use the same techniques and concepts in almost any game development environment. Written in simple language i.e. Tightly coupled code is also harder to reuse because it can't be separated. This means that one object doesn't directly change or modify the state or behavior of another object. COUPLING and COHESION COUPLING An indication of the strength of interconnections between program units. Attention reader!
