If you'll disassemble the class file, you'll notice that classes are anyways referenced using their fully qualified names (i.e. Buffered Reader instead of simply Buffered Reader).Hope its helps people and now hopefully there will be less questions on how to read and write to a file and editing data within a file :) comments on the code are welcome, but before everyone complains that i used the scanner class to read in a file i did provide the other method too, why you may ask? The imports are anyways used to manage/locate compile time dependencies.So in this code snippet I have put all these problems into one small program in hopes to help others.So this code snippet will ask for the name of a file, it will then read it in fully, after reading it will ask you to type in the contents of the line you would like to edit, it will then ask you for the replacement text.
