How to make an input in Java, when the code is running (Custom input/Key input)?

Question

Do you know Pascal?? The next generation of Java free compilable Code Program. This code program has a free input. So I want to know if Java have a free input too, Thank you..

Answer 1

You can do that with java as well.
If your program is asking for a user input then as long as it is not provided to it, the program cannot execute further.

Let me know if I did not get the question. Also what is a free input?
