CHAPTER 24 — File Input Techniques

Most programs read their data from one or more files and write their results to one or more files. Usually interaction with the user is done only to specify details of the processing, such as the names of the files. This chapter discusses some useful techniques for processing data from an input file.

Chapter Topics:

• Three types of input loops
• Counting input loops
• Several groups of data in one file
• Sentinel controlled input loops

The programs in this chapter read and write disk files using Scanner and PrintStream as described in Chapter 23.
