I guess there are two main ways to solve this task: -using StringBuilder class and its methods -manual reversing. The last one is also pretty simple, let's use KISS methodology. Each string is in fact array of chars. So just reverse that array, and then yet again convert to string. Also don't forget to google, just type "how to reverse string java" and you will get thousands of possible variants.

You simply read a filename from the counsel. Open the file with a FileReader. Read each line in the file. Reverse the order of the charaters in each line. Print out the the reversed string. Close the FileReader.
