Java™ How To Program (Early Objects), Tenth Edition

15.4 Sequential-Access Text Files

Next, we create and manipulate sequential-access files in which records are stored in order by the record-key field. We begin with text files, enabling the reader to quickly create and edit human-readable files. We discuss creating, writing data to, reading data from and updating sequential-access text files. We also include a credit-inquiry program that retrieves data from a file. The programs in Sections 15.4.1–15.4.3 are all in the chapter’s TextFileApps directory so that they can manipulate the same text file, which is also stored in that directory.
