Multiple things are wrong with this code:

  1. Variables are defined but never used
  2. Variables are used but never defined
  3. Exceptions are not caught and methods are not declared to throw them.
  4. Method names are meaningless. You try to explain what the method does in each Comment why not give the method an appropriate name
  5. In some switch's you define a single case multiple times, break is missing
  6. At some point you try to compare a String using != you should use equals instead
  7. You are creating multiple readers reading from System.in as soon as one of them is closed the other ones will throw an Exception since the underlying stream will be closed as well. Use a single scanner / BufferedReader and pass it throughout the methods or create a separate method to prompt the user for input as well as return said input.
  8. You are reading a file over and over again. Store the contents of the file once (if it is not too large) and use the data structure you stored it in (could be a List or an Array for example) to get information instead of relying on IO operations
  9. Some method like Integer.parseInt are called without storing the input therefor making them useless.
  10. Remove duplicate code in the methods and create methods for it although if you follow the advice listed above this should resolve itself to some extend
