I have a method which reads a file and returns a string, but I wanted to return a reader. I want to convert the string to a reader, or I want to read the file and return the reader. How can I do this?

Use
java.io.StringReader:return new StringReader(string);.Next time you need a reader, you can check the “Direct known subclasses” of the
Readerclass. Same goes forInputStream, etc. The place to start is the javadoc – it contains quite a lot of useful information.But for your task at hand, you’d better follow Jon Lin’ advice of simply using a
FileReader. There is no need to go throughString. (For that, my advice from the previous paragraph applies as well)
