    <p>So, I've been working on some code for my computer science course to calculate heat index. I'm having troubles loading the data from the text file I'm instructed to work with into the array the program is going to be working with. The block you see commented out is another solution I was trying, which doens't work either... How should I go about fixing it? Thanks!</p> <pre><code>import java.util.Scanner; import java.io.File; import java.io.IOException; public class HeatIndex { public static void main(String [] args) throws IOException { Scanner keyWestHumidScan = new Scanner(new File("KeyWestHumid.txt")); Scanner keyWestTempScan = new Scanner(new File("KeyWestTemp.txt")); int counter1 = 0; int counter2 = 0; int [] keyWestHumid = {}; double [] keyWestTemp = {}; String header1 = " Heat index: Key West, Florida "; String header2 = "\n Months \n "; String [] months = {"Jan ", "Feb ", "Mar ", "Apr ", "May ", "Jun ", "Jul ", "Aug ", "Sep ", "Oct ", "Nov ", "Dec ", "Avg \n"}; String header3 = "*************************************************************************************"; String [] Labels = {"Temp (F) \n", "Hudimitiy (%) \n", "HI (F) "}; //read keyWestHumid into array while(keyWestHumidScan.hasNext()) { keyWestHumid[counter1] = keyWestHumidScan.nextInt(); counter1++; //String data1_parse = keyWestHumidScan.next(); ///int data1 = Integer.parseInt(data1_parse); //keyWestHumid[counter1] = data1; //counter1++; } //read keyWestTemp into array while(keyWestTempScan.hasNext()) { String data2_parse = keyWestTempScan.next(); double data2 = Double.parseDouble(data2_parse); keyWestTemp[counter2] = data2; counter2++; } System.out.println(header1); System.out.print(header2); for(String headData:months) { System.out.print(headData); } System.out.println(header3); for(String headData:Labels) { System.out.print(headData); } } } </code></pre>

    1. COkeyWestTemp is of size 0. If you don't know the size your array will be when you create it, use a List instead (the usual implementation is ArrayList)

    2. COThe exception will tell you which line it occurred on, the index you were trying to get, and the size of the container. Use that to figure it out or at least tell us those 3 things.

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.
