Key Differences
Groovy is a dynamic language that runs on the Java Virtual Machine (JVM) and integrates seamlessly with Java. It is designed to enhance developer productivity with a simpler syntax and support for scripting capabilities. Java, on the other hand, is a statically typed language known for its "write once, run anywhere" philosophy. It is widely used for building large-scale enterprise applications due to its robustness, security features, and extensive libraries and frameworks.
While Groovy is often favored for rapid development and scripting due to its flexible and expressive nature, Java is preferred for building high-performance, scalable applications with strong type safety. Groovy can be particularly useful for writing tests, small utilities, and integrating with Java code, whereas Java is the go-to choice for developing large, mission-critical systems.
Groovy's seamless interoperability with Java allows developers to leverage existing Java libraries and frameworks, enhancing its utility as a complementary language in a Java ecosystem. Conversely, Java's widespread adoption and mature ecosystem make it a staple in software development, especially for enterprise-level applications.

Groovy
Groovy (or, less commonly, groovie or groovey) is a slang colloquialism popular during the 1950s, '60s and '70s. It is roughly synonymous with words such as "excellent", "fashionable", or "amazing", depending on context.

With a population of 147.7 million (Java only) or 151.8 million (including the inhabitants of its surrounding islands, principally Madura), Java constitutes 56.1 percent of the Indonesian population and is the world's most-populous major island.
