Java files are source code so it is just the same as a text file. Look inside the file and you can easily see how to do it.

Here is what is expected by enquirers:
1. TRY first what you want to do!
2. Formulate what was done by you that looks like an issue/not working.

Try them and tell if you face issues.

is'nt the file reader used for opening textfiles only?

a java source file with the extension *.java is basically text file.
A *.jar file is a compiled file and should not be read - therefor is a source provided if open source.
