Accepted Answer

Packages in Java, are the collection of related classes and interfaces which are bundled together. By using packages, developers can easily modularize the code and optimize its reuse. Also, the code within the packages can be imported by other classes and reused. Below I have listed down a few of its advantages:

1) Packages help in avoiding name clashes
2) They provide easier access control on the code
3) Packages can also contain hidden classes which are not visible to the outer classes and only used within the package
4) Creates a proper hierarchical structure which makes it easier to locate the related classes
