As we know, Nashorn has been deprecated, and we must consider the modern alternatives available. What do you think this change means for Java developers?
I guess they need new tools for scripting, right?
Yes! It also means they might need to learn new languages or frameworks.
Exactly! Let's explore some of these alternatives today. We'll start with GraalVM. Can anyone guess what a 'polyglot VM' means?
Does it mean it can work with multiple programming languages?
That's right! 'Polyglot' refers to the ability to support multiple languages within the same environment. GraalVM allows coding in JavaScript, Python, Ruby, and more. Shall we explore Jython next?
GraalVM is designed to run applications with high performance. Can anyone think of a scenario where having multiple language support would be beneficial?
Maybe in a project where different teams use different languages?
Great point! This versatility enables teams to collaborate better. Now, what about Jython? How does it help Java developers?
It allows them to use Python, which is popular and has many libraries, right?
Correct! Jython acts as a bridge between Java and Python, allowing the use of Python libraries in Java applications.
Let's talk about Groovy next. Does anyone know how it differs from the other alternatives?
I think it's like a simpler version of Java?
Yes! It can be less verbose and often easier to write.
Exactly! Groovy simplifies Java applications while retaining compatibility. Now, what about BeanShell?
BeanShell feels familiar since it uses Java-like syntax.
Right again! BeanShell makes it easy for Java developers to pick up, combining ease of use with Java's syntax.
So, to recap, we explored four alternatives to Nashorn: GraalVM, Jython, Groovy, and BeanShell. Each has its unique advantages. What would you say is the key takeaway from our discussion?
That there are flexible options for integrating different languages into Java.
And it's good to know what fits best based on project needs!
Absolutely! Choosing the right tool can enhance both collaboration and development speed. Great job today everyone!
Using GraalVM, developers can seamlessly integrate Java and JavaScript code to enhance applications.
With Jython, a Java application can utilize a Python library to perform complex data analysis.
Groovy can reduce boilerplate code in Java applications, enabling faster development.
BeanShell allows for quick scripting without dealing with the complexity of a full-fledged Java environment.
GraalVM can spin languages like a web, while Jython brings Python to your Java bed.
Once in a coding town, the developers faced a frown when Nashorn was no longer around. They found GraalVM with its polyglot grace, and soon their Java code picked up the pace! Jython joined in the dance, bringing Python to enhance their chance. Groovy came, lightening the flow, while BeanShell was quick to bestow.
Remember GraalVM, Jython, Groovy, BeanShell - G, J, G, B - 'Going Just Great Buddies!'.
GJGB: GraalVM, Jython, Groovy, BeanShell - Think of it as your 'Great Java Growth Buddy'.

A high-performance runtime that provides support for multiple programming languages, enabling polyglot applications.
An implementation of Python that runs on the Java platform, allowing the integration of Python scripts in Java applications.
A dynamic language for Java platform that simplifies coding while maintaining compatibility with Java syntax and libraries.
A lightweight scripting language for Java that offers a syntax similar to Java, making it easy for developers to learn and use.
With the deprecation of Nashorn, several modern alternatives provide Java developers with robust scripting options.
Nashorn, previously the default JavaScript engine in Java, is now deprecated. Several alternatives such as GraalVM, Jython, Groovy, and BeanShell offer developers advanced capabilities for integrating scripting languages into Java applications, ensuring flexible and dynamic software development.
With the deprecation of Nashorn as of Java 11, developers need to explore other modern alternatives for incorporating scripting within their Java applications. Several robust solutions have emerged:
These alternatives maintain the flexibility and dynamic capabilities originally introduced by Nashorn, providing developers with various options to enhance their Java applications' configurability and extensibility.
