How to Retrieve Class Name from Static Method in Java

When working with static methods, it's often necessary to obtain the name of the class from within the method. This article explores a method for achieving this functionality.

Consider the following code snippet:

public class MyClass {
    public static String getClassName() {
        String name = ????; // what goes here so the string "MyClass" is returned
        return name;
    }
}

The goal is to retrieve the class name "MyClass" within the getClassName() method. To achieve this, we can leverage the class property of the class:

MyClass.class.getName();

This expression returns the fully qualified class name, including the package name. For example, it would return "com.example.MyClass" if the class was defined within the "com.example" package.

If you only需要 the class name without the package, you can use the getSimpleName() method instead:

MyClass.class.getSimpleName();

This method returns only the class name, which is "MyClass" in this case.

By utilizing these methods, you can easily retrieve the class name from within a static method, ensuring that it remains consistent even after refactoring operations such as class renaming.
