在文本不断打印到控制台时读取用户输入（无诅咒？）

Question

I'm trying to print text to the console while at the same time, reading user input. But every time I do that while typing the user input usually gets cut in half by output. I would rather not use curses as an option because that just seems overkill for what I'm trying to do, as I would only be using it to grab user input.

[Log] This is a log 
input

[Log] This inpis a log 
ut

I've also seen a Windows only solution, but that doesn't help me much. Are there any libraries to do this in a multiplatform way?

Answer 1

To do this using Java, you are going to need to use Threading .

Java Threading docs .

Oracle concurrency tutorial .

Check out this similar answer , I think it will put you in the right direction:

Basically , you will have your main program running, and a Thread running. They will run simultaneously. I think it'd be simplest to have the Thread do the printing, and your main program do the input.

One caveat: If you want your program to be able to print different things (not just repeat the same println()), you may need to stop the previous Thread and kick off another when you want it to say different things.

I hope that helps!
