What is the relationship between Groovy and Java?

Groovy is a dynamic programming language based on the Java platform, with syntax and functionality that is very similar to Java. In fact, Groovy code can be run directly in a Java environment and seamlessly integrated with Java code.

Groovy has a more concise syntax compared to Java, supporting advanced features such as closures, dynamic typing, and metaprogramming, which allows for faster and more flexible code writing. Additionally, Groovy also provides many enhancements to the Java API, making it easier to use Java libraries and frameworks.

Groovy can access classes and methods in Java, and vice versa. This means that Groovy code can directly call Java code, and Java code can also call Groovy code. Therefore, Groovy can seamlessly integrate with existing Java code libraries without requiring any additional configuration or modifications.

In short, Groovy is an enhanced programming language built on top of the Java platform, closely related to Java, allowing for mutual calls and integration with Java code and providing Java developers with more flexibility and convenience.
