- in java' Variables fStream and dataFS are FileInputStream and Scanner, respectively. String fileName is assigned a file's name read from input. Perform the following tasks: Assign fStream with a FileInputStream that opens the file fileName for reading. Assign dataFS with a Scanner created using fStream.
