1. Groovy is a dynamic programming language that runs on the Java Virtual Machine (JVM) and is compatible with Java code. It is an object-oriented language that supports features such as closures, dynamic typing, and operator overloading.

    Here are some steps to get started with Groovy:

    1. Install Java Development Kit (JDK) - Groovy requires JDK version 8 or higher to be installed on your system. You can download the latest version of JDK from the Oracle website.

    2. Download Groovy - Once JDK is installed, you can download the latest version of Groovy from the official Groovy website. Extract the downloaded archive to a location on your system.

    3. Set Environment Variables - You need to set the GROOVY_HOME environment variable to the location where you extracted Groovy. Additionally, add the bin directory under GROOVY_HOME to your system's PATH environment variable.

    4. Verify Installation - To verify that the installation was successful, open a command prompt or terminal and type "groovy -v". This should display the version of Groovy installed on your system.

    5. Write Your First Groovy Program - Now that you have installed Groovy, you can start writing your first program. Open a text editor and create a file named "HelloWorld.groovy". Add the following code to the file:

class HelloWorld {
   static void main(String[] args) {
      println "Hello, World!"
   }
}

Save the file and open a command prompt or terminal. Navigate to the directory where you saved the file and run the following command:

groovy HelloWorld.groovy

This should output "Hello, World!" to the console.

Congratulations, you have successfully written and executed your first Groovy program!
