    Default Beginner struggling with homework question

    Hello, I'm struggling with this java programming question

    Create a class named Invoice that holds an invoice number, balance due and three fields representing the month, day, and year that the balance is due. Create a constructor that accepts values for all five data fields within the constructor, assign each argument to the appropriate field with the following exceptions:
    -if an invoice number is less than 1000, force the invoice number to 0
    -if the month field is less than 1 or grater than 12, force the month field to 0
    -if the day field is less than 1 or greater than 31, force the day field to 0
    -if the year field is les than 2011 or greater than 2017, force the year field to 0

    In the invoice class, include a display method that displays all the fields on an Invoice object.

    I'm completely lost on what to do next. Hope you guys can help, this is what I currently have

    public class Invoice{
    private String month,day,year;
    private double BalanceDue;
    private double InvoiceNumber;
    public Invoice(String m, String d, String y, double balance, double number){
    m=month;
    d=day;
    y=year;
    balance=BalanceDue;
    number=InvoiceNumber;}
    }

    First off you need to switch around your assignment statements. Your constructors purpose is to set the values of the object to that of the parameters passed to it.
