What is the difference between private access and package access?

Short Answer

Expert verified
Answer: Private access is the most restrictive access level, allowing data or methods to be accessed only within the same class. Package access (default access) is less restrictive, as it allows data or methods to be accessed within the same package, but not outside of it. Private access is used to protect specific data or methods, while package access is for sharing within the package without permitting public access.

Step by step solution

01

Introduction to Access Levels

In programming, access levels determine which parts of your code can access other parts. This is important because it helps maintain security and control over your code. There are several access levels that can be set. In this exercise, we will discuss private access and package access.
02

Private Access

Private access level is the most restrictive access level, which means that the data or method declared as private can only be accessed within the same class. No other parts of your code can access it directly. This level of access is used when you want to restrict access to specific methods or data, useful for maintaining the integrity of your code.
03

Package Access

Package access (also known as default access) is less restrictive. When you do not specify any access level, the method or data has package access by default. This means that it can be accessed within the same package, but not outside of it. This level of access is helpful when you are writing code that is closely related and want to share certain parts of your code without making them fully public.
04

Key Differences

Here are the key differences between private and package access: 1. Private access is more restrictive than package access, only accessible within the class itself. 2. Package access is the default access level and allows access to data and methods within the same package. 3. Private access is used when you want to protect specific data or methods within your class, while package access is for sharing within the package but not permitting public access. By understanding the differences between private access and package access, you can create code that is secure, maintainable, and efficiently organized.
