Questions about the idea of the code

Hello,
I have homework in java, I just want to ask you some questions ( I don't want the whole code ).
A company has four salespeople (numbered from 1 to 4), who sell five different products (numbered from 1 to 5). Once a day, each salesperson passes in a slip for each type of product sold. Each slip contains the following:
 The salesperson number,
 The product number,
 The total value of that product sold that day.
1. Propose a class Slip to store the data of sales slips.
2. Each salesperson passes in between 0 and 5 sales slips per days. Propose an array, slips, to store the data of sales slips for a whole month (31 days). Assume that the total value of each product never exceeds 99$. Write a method, collectSlips, to collect the sales information for a month by randomly filling the slips array.
3. Write a method, summarizeSalesSlips, that will read all this information for one month’s sales and summarize the total sales by salesperson and by product. All the totals should be stored in sales, a two dimensional array.
_______________________________________________

About Q2:
I did 3 for - loops.
1) start from 1 ---> 31 ( number of days )
........ 2) start from 1 ---> 4 ( number of Employees )
............... 3) start from 0 ---> 5 ( number of products )
set the values (salesperson number, product number, total) randomly

My questions are:
1) what is the appropriate size of the array as the numbers are creating randomly ( included zero in number of products)
2) Is my idea in Question 2 correct?
3) How to do the methode of summarizeSalesSlip - I mean the idea - ?

Thank you :D

Try coding and testing one step at a time, first build and test the slip class and move on from there. Are you sure sales people should be turning in slips for items they didn't sell?

As for question 3 of the assignment that can be done fairly easily with loops on the 2d array and if else clauses.

Are you familiar with OOP.then OOp can make this problem easier.

Do something like this...

Code:

---

class slip{
int productnmbr;
double totalvalueofthatproducr


}


class salesman{
slip slipobj[5];


}

public class MAIN{

public static void main(String a[]){

salesman salesperson[4];
}

}
