What is the use of package in java

Package is used to organize and encapsulate related classes and interfaces in Java. Its main uses include: 1. Provide a unique name space to avoid conflicts; 2. Control class accessibility; 3. Organize code and improve modules ization; 4. Promote code reuse; 5. Improve maintainability.

The purpose of package in Java

In Java, package is used to organize and encapsulate related classes and interfaces . Its main uses are as follows:

1. Namespace:

• package provides a unique namespace to avoid class and method name conflicts. It allows you to create different classes with the same name as long as they are in different packages.

2. Accessibility control:

• package controls the accessibility of classes to a certain extent. By default, all classes in the same package can access each other's members. However, you can further restrict access through access modifiers.

3. Organization and modularization:

• #package organizes the code into logical groups, making the code easier to manage and understand. It allows you to group related classes and interfaces into a single namespace.

4. Code reuse:

• package promotes code reuse. You can encapsulate common functions and utilities in a package and easily import and use them in other projects.

5. Maintainability:

• By using packages, you can improve the maintainability of your code. It enables you to easily find and modify related modules without worrying about name conflicts or accessibility issues.

Note:

• Classes and methods of the default package (no package specified) are visible throughout the project.
• You can use the import statement to import classes and interfaces in multiple packages.
• Build tools such as Maven and Gradle use packages to organize and manage code dependencies.
