How to convert String to Reader in java
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 Reader
class. Same goes for InputStream
, 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 through String
. (For that, my advice from the previous paragraph applies as well)
Or you can simply create a FileReader and return that.
You can use StringReader class from java.io
package.
String stringToBeParsed = "The quick brown fox jumped over the lazy dog";
StringReader reader = new StringReader(stringToBeParsed);
