We are Hiring! Introduction to Java Java is one of the world's most important and widely used computer languages, and it has held this distinction for many years.
Evolution of Java Java was initially launched as Java 1. Association Association represents the relationship between the objects.
Here, one object can be associated with one object or many objects. There can be four types of association between the objects: One to One Many to One, and Many to Many Let's understand the relationship with real-time examples.
For example, One country can have one prime minister one to one , and a prime minister can have many ministers one to many.
Also, many MP's can have one prime minister many to one , and many ministers can have many departments many to many. Association can be undirectional or bidirectional. Aggregation Aggregation is a way to achieve Association.
Aggregation represents the relationship where one object contains other objects as a part of its state. It represents the weak relationship between objects.
It is also termed as a has-a relationship in Java. Like, inheritance represents the is-a relationship. It is another way to reuse objects. Composition The composition is also a way to achieve Association. The composition represents the relationship where one object contains other objects as a part of its state.
There is a strong relationship between the containing object and the dependent object. It is the state where containing objects do not have an independent existence.
If you delete the parent object, all the child objects will be deleted automatically. Advantage of OOPs over Procedure-oriented programming language 1 OOPs makes development and maintenance easier, whereas, in a procedure-oriented programming language, it is not easy to manage if code grows as project size increases. We can provide the solution of real word problem if we are using the Object-Oriented Programming language.

Parameters can match to int, or Integer or simply String also. Here java takes care of converting simple statements to machine language and hides the inner implementation details from the outer world.
Aggregation represents the relationship where one object contains other objects as a part of its state. The composition represents the relationship where one object contains other objects as a part of its state.
