Well, i've got another question. I am using a char to ask user to answer a question in yes or no. If the user enters y or n, i want to show the entire word Yes or No before the user can type it. How can i do that?
Btw, i couldn't edit the previous posts so i had to post again. |

not sure what u mean by that. I want to print Yes on the screen and wait for the user to press enter if the user presses y or print No on the screen and wait for the user to press enter if the user presses n.

you can do that with a keylistener, if y is pressed then System.out.println("Yes");
and so on..

I don't think you can do that in the console. It always waits for an enter at the end of the line, tu execute a command.
So, i don't think you can do what you want.

Any useful site or a tutorial that might be able to help me figure out how to use KeyListener?

i've got it!!! if you can't win, cheat!!
 create a jframe, but make it invisible [setVisible(false)] and then add a keylistener to it. check sun's tutorial. just quickly got this. didn't go through it, but i'm sure you can find something there, but if you don't, then let me know. http://java.sun.com/docs/books/tutor...ylistener.html what will happen then, is the user will read what the console window and then do whatever he wants. the jframe will be taking in what he enters, and then you'll put what he types on the console window with System.out.print( characterEntered ). you can now take a y that he enters and turn it into a "YES"!!! WOW!!! i am so freaking amazing i scare myself! i'll go play with the idea and see if i can get it to work.
