Built-in-Annotations-Java

Built-in annotations in Java are predefined metadata markers that provide essential information to the Java compiler and various tools. These annotations enhance code readability and maintainability by allowing developers to convey specific instructions or constraints without altering the actual code structure. Common built-in annotations include @Override, which indicates that a method is intended to override a method in a superclass, and @Deprecated, which marks elements that should no longer be used. Understanding and utilizing these annotations can significantly improve code quality and facilitate better collaboration among developers by ensuring adherence to coding standards and practices.
