Java coding for user input?

You only see java.io.* on an import statement. That just says, "Import all of the classes defined in the java.io package."

The java.io package has all of the basic I/O classes. If you want to peek at what http://docs.oracle.com/javase/7/docs/api/index.htm...

That's quite a lot. If you plan to use Java for serious work, get used to looking things up there. You can navigate using the left frames to select a specific package, or "All Classes" on the top left, then find the class you want on the bottom left. And so on.

A quicker index, if you know the class name, is a web search for "java 7 scanner", substituting any standard class name for for "scanner" (and you don't want quotes in your search.) What you want is almost always the first hit.

The Scanner class is not part of the java.io package though. That's probably because it also operates on String input. Scanner is in the java.util package.

For console I/O, you can use Scanner on the System.in object for all of your input, and any PrintStream methods on the System.out object for all console output.

A simple example (assuming java.util.Scanner or java.util.* has been imported):

Scanner sysin = new Scanner(System.in);

System.out.print("Tell me your name: ");

String name = sysin.nextLine(); // input whole line for name

System.out.print("How old are you? ");

int age = sysin.nextInt();

System.out.println("Hi " + name + ".");

System.out.println("You are " + age + " years old today.");

Wrap that in a class and a main() method and give it a try.

Only answer, and yet I don't think anyone else could have said it any better. Thank you!
