    <p>The code works and was pretty easy. I made another using a switch but teacher wants if statements. So the user enters 2 numbers then makes a choice after from the println menu I created. I need the user to be able to make a second choice. Such as choose "a" for addition then also being able to choose "b" subtraction afterwards. It would be nice to be able to make the menu reproduce after every choice was made also. I need the first user input numbers to be persistent.</p> <p>thanks. edit: this is final version that works</p> <pre><code>import java.util.Scanner; public class Assign3 { public static void main (String [] args) { double numOne; double numTwo; String answerTo = null; System.out.println("============================"); System.out.println("| MENU Calculator Fun |"); System.out.println("============================"); System.out.println("| Options: |"); System.out.println("| a. Add |"); System.out.println("| b. Substract |"); System.out.println("| c. Multiply |"); System.out.println("| d. Divide |"); System.out.println("| e. Mod |"); System.out.println("| f. Compare |"); System.out.println("| g. Print Numbers |"); System.out.println("| h. Quit |"); System.out.println("============================"); Scanner numFinder = new Scanner(System.in); System.out.println("Please enter a number then press enter then enter another number followed by enter."); numOne = numFinder.nextDouble(); numTwo = numFinder.nextDouble(); while(true) { Scanner scan = new Scanner(System.in); System.out.println("Please choose an option."); String menuSelect = scan.next(); if(menuSelect.length() &gt; 1) { System.out.println("Error, too many letters..."); } else if(menuSelect.equals("a")) { answerTo = Double.toString(numOne +numTwo); } else if(menuSelect.equals("b")) { answerTo = Double.toString(numOne - numTwo); } else if(menuSelect.equals("c")) { answerTo = Double.toString(numOne * numTwo); } else if(menuSelect.equals("d")) { answerTo = Double.toString(numOne / numTwo); } else if(menuSelect.equals("e")) { answerTo = Double.toString(numOne % numTwo); } else if (menuSelect.equals("f")) if(numOne &gt; numTwo) { answerTo = "&gt;";//System.out.println("First is grater"); } else if(numOne &lt; numTwo) { answerTo ="&lt;";//System.out.println("Second is grater"); } else { answerTo ="=";//System.out.println("Both are equal"); } else if(menuSelect.equals("g")) { answerTo = "First number: " + numOne + " Second number: " + numTwo; } else if(menuSelect.equals("h")) { break; } System.out.println("answer: " + answerTo); } } } </code></pre>

    2. COI learn mostly on my own and I have allot more experience with c# and VB. So I have tried to input a while(true) but the end statements run infinitely. So I figured I needed help with implementing the while statement.

    3. CO`while(true)` could work, but you'll have to have `if(menuSelect.equals("h")) break;` if that makes sense

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.
