Understanding the Importance of Naming Methods as Strings in Java 11

In Java 11, developers can now name methods as strings, which offers several benefits and can greatly improve the flexibility and maintainability of code. This feature allows developers to dynamically invoke methods based on their names stored in string variables. In this article, we will explore why naming methods as strings is important and how it can be leveraged effectively in Java 11.

Dynamic Method Invocation

Traditionally, method invocations in Java are static where the name of the method is known at compile-time. However, there are scenarios where the method name needs to be determined dynamically at runtime. This is where naming methods as strings becomes valuable.

By storing method names in string variables, developers have the ability to invoke different methods based on user input or other runtime conditions. This opens up a wide range of possibilities for creating more flexible and interactive applications.

Improved Flexibility

One of the key advantages of naming methods as strings is improved flexibility. With this approach, developers can easily switch between different sets of methods without modifying their code extensively. For example, if you have a program that performs various mathematical operations such as addition, subtraction, multiplication, and division, instead of writing separate blocks of code for each operation, you can store the method names in string variables and dynamically invoke them based on user input or other conditions.

This flexibility also extends to dynamic loading of classes and invoking their methods using reflection. You can load classes at runtime by specifying their fully qualified names as strings and then invoke their methods using this approach. This enables you to extend your application’s functionality without recompiling your code or modifying existing logic.

Enhanced Maintainability

Naming methods as strings also improves code maintainability by reducing duplication and increasing reusability. With this approach, you can create generic functions that accept method names as parameters and reuse them across different parts of your codebase.

For instance, let’s say you have a utility class that performs various file operations such as reading, writing, and deleting files. Instead of writing separate methods for each operation, you can create a single method that accepts the desired operation as a string parameter. This way, you can reuse the same method for different file operations without duplicating code.

Furthermore, naming methods as strings simplifies the process of adding new functionalities to existing code. Instead of modifying existing logic or introducing conditional statements, you can simply add new methods with unique names and dynamically invoke them based on the given string parameter. This makes your code more modular and easier to maintain in the long run.


Naming methods as strings in Java 11 provides developers with dynamic method invocation capabilities, improved flexibility, and enhanced maintainability. It allows for more interactive and adaptable applications by enabling runtime determination of method invocations based on user input or other conditions.

By leveraging this feature effectively, developers can reduce code duplication, increase reusability, and simplify the addition of new functionalities. As a result, their code becomes more modular and easier to maintain over time.

In summary, naming methods as strings is an important feature in Java 11 that empowers developers to write more flexible and maintainable code. It opens up possibilities for creating dynamic applications that can adapt to changing requirements without extensive modifications.
