CHAPTER 11 — Floating-point Input and Output

Floating point input using java.io is fundamentally like integer input. With floating point, as with integers, you first read in characters. Then, if the characters are correctly formatted, they are converted to a numeric type.

Chapter Topics:

• Converting strings to double.
• Keyboard input of floting point numbers.
• Fill-in-the-blank Story Problems.

The methods in this chapter work only with Java versions 1.2 and higher. If you have an earlier version of Java you can skip this chapter without significant loss.
