What is package in Java?

Today we discuss about the package in java oops concepts.

1. A package is a namespace + folder that groups related classes and interfaces. - Package = folder for classes

Example:

If you organize them based on purpose.

• User, Admin, Customer → com.app.model

• UserService, OrderService → com.app.service

• UserController → com.app.controller

2.Think of it as a folder in a file directory.

Physically, yes — it becomes a folder.But logically, it’s more than that.A package is a namespace.

com.bank.User
com.school.User

3.We use packages to avoid name conflicts.

• Without packages:

If two developers both create a class named User, your project breaks.

• With packages:

They can exist peacefully in different namespaces.

4.Better maintainable code:

Maintenance means:

• Easy to find classes

• Easy to update

• Easy to debug

• Easy for new developers to understand structure.
