Packages in Java: How You and I Organize Our Code

Packages in Java are a way to group related classes and interfaces together in an organized manner. Think of them as folders that help keep our codebase clean and manageable. For example, if we create a package named development, it can include all the classes and interfaces related to development tasks. By using packages, we not only avoid name conflicts but also make our code easier to navigate, especially in large projects.

A Java package is a group of similar types of classes, interfaces, and sub-packages. Package in java can be categorized in two forms, built-in package, and user-defined package. There are many built-in packages such as java, lang, awt, java, swing, net, io, util, SQL, etc.

The main use of packages is
1) To resolve naming conflicts
2) For visibility control: We can define classes and interfaces that are not accessible outside the
class.

Advantages of Java Package

• Java package categorizes classes and interfaces, making them easy to maintain.
• Java packages offer access protection.
• Java package eliminates naming collisions
