    Default Ordering Inputted Java Values


    I am trying to make a prioritizer that asks for a number of values from the user using JOptionPane. The program uses a simple algorithm to calculate a numerical value. The higher the value, the more important it is to do a certain task.

    To assist in the recognition and ordering of each task, I asked for the name (nameOfTask). This is when it became difficult. I wanted to attach a numerical value to the String nameOfTask so that when I output the tasks in order of importance only the String nameOfTask is shown. I do not want the numerical value associated with that name to be shown. Am I approaching this incorrectly?

    The main objective, if I haven't made this clear, is to order these String variables based on a numerical value.

    So far, I have coded so that a numerical value can be identified but I don't know where to go from there. Here is an oversimplified version of my code:

    Java Code:
        String nameOfTask;
        double importanceOfTask;
        double amountOfTime;
        double total;
    public void calculatePriority()
            this.nameOfTask = JOptionPane.showInputDialog("What is the task? ");
            String amountOfTime = JOptionPane.showInputDialog("How many minutes will the task take you? ");
            this.amountOfTime = Double.parseDouble(amountOfTime);
            String importanceOfWork = JOptionPane.showInputDialog("How important is this task? 1-10? \n(One being least important) ");
            this.importanceOfWork = Double.parseDouble(importanceOfWork);
            total = (amountOfTime * 2) + (importanceOfWork)
    I would then like to output the task in order, highest to lowest, showing only the name of the task. For example:

    Order of tasks:
    1. Do dishes
    2. Vacuum
    3. Wash car

    Thank you for the help!

    Don't stick the UI stuff in the class.
    You should be able to write this class without that.
    Make the UI the job of another class.

    You'll also want a Comparator (or make this Comparable), that way you can add this into a List and order it easily.
    Please do not ask for code as refusal often offends.

    Absolutely not an 'advanced' topic. Moving to New to Java
