Question

So I want to make a java application which, while running, can run custom commands (not windows commands, commands for my application) from the command line, I can already do it, but I’d like to have a prompt such as > where you’d type commands, how can I output > and then remove it when it’s time to print something else to that line?

Answer 1

On Java 6, you can use the Console class for that. Specifically, the readLine method. From the API:

public String readLine(String fmt, Object… args)

   Provides a formatted prompt, then reads a single line of text from the console.
