The main reason to use composition is that it allows you to reuse code without modeling an is-a association as you do by using inheritance . That allows stronger encapsulation and makes your code easier to maintain as Joshua Bloch explains in the 3rd edition of his book Effective Java.16 Oca 2018

Read moreWhat is the difference between composition and inheritance?
Inheritance and composition are two programming techniques developers use to establish relationships between classes and objects. Whereas inheritance derives one class from another, composition defines a class as the sum of its parts .

Read moreIs a relationship example?
For example, if a class Bulb inherits another class Device, then we can say that Bulb is having is-a relationship with Device , which implies Bulb is a device.
Read moreWhat is difference between aggregation and composition in Java?
Aggregation implies a relationship where the child can exist independently of the parent . For example, Bank and Employee, delete the Bank and the Employee still exist. whereas Composition implies a relationship where the child cannot exist independent of the parent.
Read moreWhy do we need composition in Java?
Benefits of using Composition: Composition allows us to reuse the code . In Java, we can use multiple Inheritance by using the composition concept. The Composition provides better test-ability of a class. Composition allows us to easily replace the composed class implementation with a better and improved version.
