    <p>assignment: A school that your little cousin attends is selling cookies. If your cousin's class sells more cookies than any other class, the teacher has promised to take the whole class on a picnic. Of course, your cousin volunteered you to keep track of all the sales and determine the winner.</p> <p>Each class is identified by the teacher's name. Each sales slip has the teacher's name and the number of boxes sold. You decide to create two parallel arrays: one to hold the teacher's names and one to record the number of boxes sold. Here is a sample of the data:</p> <p>The first number gives the number of classes, and then a teacher's Name is followed by the number of boxes sold 15 Smith 3 Courtney ... so on so forth<br> <br><br> My main issue (because i can just duplicate it for the "to-be" parrallel array) is getting every other line to save into an array for the boxes sold so array "boxSold" would look like <br><br> [1] 15 <br> [2] 3</p> <pre><code> package assignment5Package; import java.util.Scanner; import java.io.*; public class assignment5Demo { /** * @param args * @throws IOException */ public static void main(String[] args) throws IOException { // TODO Auto-generated method stub //create arrays, variables Scanner keyboard = new Scanner(System.in); BufferedReader input = new BufferedReader (new FileReader ("/Users/lee/Desktop/class/cs 113/Assignment5/cookies.txt")); System.out.println("How many sale slips are there"); int numSaleSlips = keyboard.nextInt(); int[] soldBox = new int[numSaleSlips]; //______String[] teacherName = new String[numSaleSlips]; int soldBoxIndex; int teacherNameIndex; //String soldBoxString; (line 50) //initializing both strings to 0 and "_" for (soldBoxIndex = 0; soldBoxIndex &lt; numSaleSlips; soldBoxIndex++) { soldBox[soldBoxIndex] = 0; } //**for (teacherNameIndex = 0; teacherNameIndex &lt; numSaleSlips; teacherNameIndex++) //**{ //** teacherName[teacherNameIndex] = "_"; //**} //reading from the cookies.txt file for (soldBoxIndex = 0; soldBoxIndex &lt; numSaleSlips; soldBoxIndex++) { if (soldBoxIndex % 2 != 0 { String soldBoxString; soldBoxString = input.readLine(); //reads in value and assigns/re-assigns soldBox[numSaleSlips] = (int) Double.parseDouble(soldBoxString); //type-casted to fit variable type, converts to double, stores in array System.out.println(soldBox[soldBoxIndex]); } else { System.out.println("Error at " + soldBoxIndex +"."); } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
