Tasks
- Explore the jtm.activity09 package
- Implement the StreamEditor class to pass unit tests
If necessary, you can use the Apache IO package (or java.nio) package instead of the default java.io.* package to make file operations easier.
You can do manual testing like this (from your project folder), for example:
java -cp target/classes/ jtm.activity09.StreamEditor 2 aaa - -
When doing manual testing, indicate the end of the stream by pressing Ctrl+d.
