    <p>This IS NOT homework, but it is a practice that the teacher gave us to help study for a test. But i will not be turning this in to the teacher. (i'm hoping that is allowed)</p> <p>He wants a user to input a grade and have it assigned a letter grade. It would be easy with if statements, but i can't use ANY! I have to use the switch method.</p> <p>Here is my functional class:</p> <pre><code>public class Grade { public double getGrade(int input) { double inputGrade; switch(input) { case 1: inputGrade &gt;= 90; break; case 2: inputGrade &gt;= 80; break; case 3: inputGrade &gt;= 70; break; default: grade = 60; } return grade; } } </code></pre> <p>Here is my test class:</p> <pre><code>import java.util.*; public class TestGrade { public static void main(String[] args) { Scanner scan = new Scanner(System.in); int input = scan.nextInt(); Grade lGrade = new Grade(); double finalGrade = lGrade.getGradeSwitch(input); System.out.println("Your toll is $" + finalGrade); } } </code></pre> <p>I just haven't been programming enough to have this analytical mind. I HAVE tried to complete it, i just haven't found a way to covert the user input (int) into a letter grade (string) without if statements.</p> <p>I know this is incomplete, but this is as far as I could go without making errors.</p> <p>EDIT:WOW! Thanks guys, i hate to pick a single correct answer, because a lot of you helped me!</p> <p>This is what i ended up with (that worked :D)</p> <pre><code>public String getGrade(int input) { String letterGrade; switch(input/10) { case 9: letterGrade = "A"; break; case 8: letterGrade = "B"; break; case 7: letterGrade = "C"; break; case 6: letterGrade = "D"; default: letterGrade = "F"; } return letterGrade; } </code></pre>

    1. COHomework is allowed, though generally it's nice if people tag it as such. Or even writing the question in such a way that shows you've put thought into it rather than just copy/paste the question out of your excercise.

    2. COAmen to what Matthew said. +1 for the effort, even though I often find homework questions less than acceptable.

    3. COWow. You have to love arbitrary rules such as "you must use a switch statement". That really reflects the real world. I mean, wouldn't it have been better if the teacher actually came up with a question more suited to actually using a switch statement. I mean, you could probably write a solution using just while loops, but you never would.

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.
