code:
char c=0;
System.out.println("Do you want to continue?y/n"+c);

why JAVA didn't let me key in y or n?

thanks for answer!

Hi,

I don't see any statements here that read input from System.in; I only see you printing a prompt. JDKs prior to 1.27 (due out in Q3 of 2014) don't have the java.ai.natural.language package, and so won't be able to automatically read the text of the prompt and figure out that you mean to have the user type something, so you'll have to explicitly do it yourself.

My friend you really need to do a basic tutorial. Try starting here:
http://java.sun.com/docs/books/tutorial/index.html

Do "Getting Started" followed by "Learning the Java Language" and go from there.
