    Default Sorting a text file into an array

    The programs runs and outputs everything perfectly

    But there is one more thing that needs to be added and I dont know where to begin.
    I now need to sort the employees into 2 arrays (2018, 2017)
    Distinguish between Employee, Salesman, and Executive
    run that employees info through their respective class

    i.e. The very first line of the "Project1.txt" file should be displayed like this after program execution
    Name: Mazzeo, Brian
    Monthly Salary: 3000
    Annual Salary: 36000

    I have a text file "Project1.txt" and it is set up like this:
    2017 Employee Mazzeo, Brian 3000
    2017 Employee Reinhart, Erik 5000
    2017 Salesman Speck, Randy 3900 95000
    2018 Salesman Gries, Alan 4000 3000000
    2018 Executive McCoy, Alex 6950 50
    2017 Executive Johnson, Matt 8000 55

    Default Re: I dont know how to connect all the pieces

    to use each of the other classes.
    Create an instance of a class with a new statement.
    Save the reference to that instance to use in calling its methods:
      SomeClass refToClass = new SomeClass(someArgs);   // create instance of class
      refToClass.aMethod();    //call one of its methods

    See the java tutorial for lots more: http://docs.oracle.com/javase/tutori...ybigindex.html


    Please edit your post and wrap your code with code tags:

    How are you debugging the code to see what the problems are?
    To see what the code is doing, add some print statements that print out the values of variables as they are used and as their values are changed.
    If you don't understand my answer, don't ignore it, ask a question.

    I think you need to take each line of input from your text file (in your while loop) and then do the following steps:
    1. split each line (by spaces) into an array of employee detail
    2. sort this array on the first field (the year)
    3. use an if or switch statement on your second field to identify employee type
    4. create each employee (by the type found above) using the other fields in your array.
    5. print out your employee detail


    try implementing this list and if you get stuck post your code and we can try and help
