    Annotations in Java are a powerful mechanism for adding metadata to your source code. They were introduced in JDK 5 and provide a way to associate information with program elements such as classes, methods, fields, and more. Annotations can be used for various purposes, including providing information to the compiler, generating code, and runtime processing.

    Basic Syntax and Usage

    Annotations start with the @ symbol, followed by the annotation name. They can include elements, which can be named or unnamed, and have values. For example:

    @Override
    void mySuperMethod() { ... }

    @Author(name = "Benjamin Franklin", date = "3/27/2003")
    class MyClass { ... }

    @SuppressWarnings("unchecked")
    void myMethod() { ... }
    പകർത്തിയിരിക്കുന്നു!

    If an annotation has no elements, the parentheses can be omitted, as shown in the @Override example.

    Categories of Annotations

    Annotations can be broadly categorized into five types:
