JLine is a Java library for handling console input, similar to GNU Readline, providing line editing, tab completion, history, and syntax highlighting for command-line applications. It is cross-platform and includes interactive UI components like menus and prompts.

Use cases

• build an interactive REPL in Java
• add tab completion to a CLI tool
• handle raw terminal input cross-platform in Java
• implement command history with search in a console app
• add syntax highlighting to shell input
• prompt for passwords with masking in Java
• build interactive console menus and prompts

When to choose

• you are building a Java command-line application that needs rich interactive input
• you need GNU Readline-like functionality with portability across Windows, macOS, and Linux
• you want customizable tab completion, history, and key bindings in a JVM app

When to avoid

• you need a non-JVM language solution
• you only need simple argument parsing rather than interactive line editing
• you are targeting Java 8 and need JLine 4.x features
