    Default Working with Arrays



    I'm having a problem with one part of this assignment, the instruction is this "Add a method transaction which takes two int parameters, daynum and amount. daynum is the day of the month, and amount is an amount of money made or lost for a transaction on that day. (hint: days of the month are numbered starting from 1, arrays arent; think about how to handle this)." this is what I have so far
     public class MonthlyRecord {
    //instance variables
        private String month;
        private double[] moneyDaily;
     
    //default constructor
        public MonthlyRecord() {
            month = "January";
            moneyDaily = new double[31];
        }
    //accessor for monthlyRecord
        public String getMonth() {
            return month;
        }
    //mutator for monthlyRecord
        public void setMonth(String v) {
            month = v;
        }
    //constructor with parameters from whatever is calling it
        public MonthlyRecord(String b, int x) {
            month = b;
            moneyDaily = new double[x];
        }
     /*Add a method transaction which takes two
      * int parameters, daynum and amount.  
      * daynum is the day of the month, 
      * and amount is an amount of money made or 
      * lost for a transaction on that day*/   
     
     
        public void Transaction(int dayNum, int amount) {
       dayNum = 0;
       amount = 0;


    It could just be because my brain feels a lttle fried for some reason, but what am I missing here to ensure this is done correctly? Thx in advance!

    Default Re: Working with Arrays

    First problem I see is that the method is incorrectly named. Java is case sensitive. T is not the same as t

    What is the method supposed to do with the values passed in its args?
    If you don't understand my answer, don't ignore it, ask a question.
