Question: 1 / 400

What is the purpose of a package in Java?

A package is a mechanism for defining new data types.

A package is a namespace that organizes related classes and interfaces.

The purpose of a package in Java is to serve as a namespace that organizes related classes and interfaces. This organization helps to group similar functionalities together, making it easier for developers to locate and manage code. By categorizing related classes in a package, Java prevents name conflicts—where two classes might have the same name—because each class is recognized within its own package context.

Additionally, packages facilitate a better structure within Java applications, as they enable a modular approach to software design. This modularity not only increases maintainability but also promotes reusability, as developers can easily share and utilize packages across different projects.

In summary, a package enhances the clarity and manageability of code by logically organizing classes and interfaces, which is essential for effective software development.
