About:
Jenv is a command-line tool for managing multiple Java versions on a per-project or global basis. It simplifies switching between different JDKs without manual environment variable configuration. This is valuable for developers working on projects requiring specific Java versions.

Key Features:

Switch Java versions globally or per-directory
Integrates with shell configuration for seamless usage
Discovers installed JDKs automatically
Lightweight and written in Bash

Use Cases:

Managing multiple Java projects with different version requirements
Automating Java version selection in CI/CD pipelines
Testing applications across different Java versions

Alternatives:

SDKMAN! – SDKMAN is more feature-rich, managing multiple JVMs and tools, whereas Jenv focuses specifically on Java version switching.
asdf – asdf is a polyglot version manager that can handle Java and other languages, while Jenv is Java-specific.
