Building a tidy string

When we use the console for our output, we can carefully format the output using the System.out.printf method. We can format the strings for a JOptionPane dialog box, too, but there are a few extra steps involved. This example shows one way to build a formatted string using a Formatter from the java.util package.

Just say no to "magic numbers"

It is unacceptable to use "magic numbers" in your source code. When dealing with trivial programs, using a naked number doesn't look like such a big deal (the code is short and, if well commented, the intent of the programmer is clear) but it is still a very bad habit to develop. The problem is both clearer to see and greatly magnified once the size of the code in question is larger.
