Question
- Now implement a method reverseSequences that takes two Strings as parameters. The first String is the name of an input file containing String values and the second is the name of an output file to write the reverse sequences to. The method should read sequences from the input file one sequence at a time using getSequence and then write them out to the output file. Do not forget to close the output file when the method is finished. Make sure you catch and handle the possible IOException exceptions.
public static void reverseSequences(String inputFile, String outputFile)
