    <p>I am learning Java and just been working on creating a little calculator. I am writing one what will allow me to put any number of digits in until I press an equals sign at which point I want the calculator to display the total.</p> <p>I think that there is a problem with the scanner as while debugging I only get as far as <code>Scanner input = new Scanner (System.in):</code> In the debugger it say Source not found. This is really strange especially as I am using two Scanners the other class within the same project with no problems at all. As you can tell I used to have 2 scanners in this piece but I read that this should not work so I am now using one. Here is the code...</p> <pre><code>package Calculator; import java.util.Scanner; public class Calculator3 { public static void main(String[] args) { Scanner input = new Scanner (System.in); // Scanner opin = new Scanner (System.in); String operative = input.next(); double numb = input.nextDouble(); int answer = 0; int calc = 1; System.out.print("#######################################" + "\n"); while (operative.equalsIgnoreCase("=")) { System.out.print("Interger " + calc + " :"); System.out.print("Type your Operative :"); if (operative.equals("+")) answer += numb; { if (operative.equals("-")) answer -= numb; { if (operative.equals("/")) answer /= numb; { if (operative.equals("*")) answer *= numb; { } } } } calc += 1; } System.out.print("#######################################" + "\n"); System.out.println("Your answer is: " + answer + "."); } } </code></pre>

    1. COYou probably are trying to step-in, so it's complaining because it's not able to find the source for `Scanner` or `System`), while debugging you should step-over.

    2. COTake a moment to read about switch/case statements. It'll help you tighten up that code.

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.
