Indexed File I/O Processor for Java Applications

Java has a robust set of file I/O classes. However, it is sometimes difficult to get all the proper I/O classes established and organized they way you need them. For instance, there are reads, writes, buffered reads, buffered writes, text, binary and objects and several more. Indeed, Java has a nice compliment of I/O functions but a lot of knowledge is needed to implement the right ones at the right time.

Plus, if you programmed back in the days of the mainframe or AS/400, you know there was a pretty clever I/O method called Indexed Sequential Access Method (ISAM). The premise for this application is the old ISAM file process where each file has a set of records with a static number of fields and a unique key field to access any given record in the indexed file.

This downloadable Java class, named Indexed IO, manages all usage and access for indexed and sequential files in a Java application. The internal data format is a set of complex objects that represent records of data fields. Each file has a set of records each of which can be accessed by a unique string key value. It's fast and can accommodate over 230,000 records in each indexed file.
