    There are plenty of code examples here on the forum. Do a Search.
    Also there are examples in the API doc for the Scanner class:

    I thought you wanted to know how to use the Scanner class. If so look for "Scanner"
    Did you look at the API doc?

    If that isn't a problem, can you explain what your problem is?

    how to get the program to close
    One way to have a program to close is to call the System.exit(0) method.

    b.toUpperCase();
    Remember that Strings are immutable (they cannot be changed). Most of the methods in the String class return a new String which you need to save somewhere.

    As to how to handle if user enters "close" use the equalsIgnoreCase method in an if statement.
