Summary of Changes
Hello @amazon-pratik, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
I've added 50 randomly selected Scala code samples from a security dataset. The primary purpose of these additions is to provide a comprehensive set of examples for analysis and testing, showcasing various security-related coding patterns.
Highlights
- New Scala Samples Directory: I've added a new directory, scala/random_samples/, to house 50 randomly selected Scala code samples.
- Purpose of Samples: These samples are sourced from a security dataset and are intended for analysis and testing of security rules.
- Documentation for Samples: A README.md file has been included in the scala/ directory to provide clear documentation on the purpose and contents of these new samples.

Code Review
This pull request adds a large number of Scala code samples for security analysis. While the samples effectively demonstrate various security vulnerabilities and compliant code patterns, many of them contain code quality issues such as compilation errors (missing imports, incorrect return types), unused variables, and typos. These issues should be addressed to improve the quality and usability of the samples. I've left specific comments on the files that need attention.

A method cannot be defined at the top level in a Scala file that contains imports. This code will not compile. The nonCompliant method should be wrapped in a class or an object.

The FileInputStream class is used but not imported, which will cause a compilation error. Please add import java.io.FileInputStream.

This class mixes Play framework constructs (extending AbstractController) with direct usage of the Servlet API (HttpServletResponse). This is confusing and not standard practice. A Play controller should typically return a Result object rather than directly writing to a HttpServletResponse.

The parameter expression is unused in the method body. It should be removed if it's not needed.

The variables map, vals, names, contentType, and serverName are declared but never used. They should be removed to improve code clarity.
