How to Read File Contents to String using Apache Commons IO
In this example we use the Apache Commons IO classes to read the contents of a file to a String. The Commons IO classes provides a neat way to do so through the FileUtils class which has a static method called readFileToString(). There's an overloaded version of that method that takes a java.io.File instance as parameter, so we need to create such an instance with the filename as argument. Then we send it to the readFileToString() method and get the content of the file read into the String, and finally we print it out. |
