Section 15.4 Sequential-Access Text Files
• Java imposes no structure on a file. You must structure files to meet your application’s needs.
• To retrieve data sequentially from a file, programs normally start from the beginning of the file and read all the data consecutively until the desired information is found.
• Data in many sequential files cannot be modified without the risk of destroying other data in the file. Records in a sequential-access file are usually updated by rewriting the entire file.
