    <p>I am making a method in order to get how many numbers the user wants to sum together. aka if they want to sum the numbers 1 2 and 3. they would want to sum 3 numbers together. So when i ask them how many they want to sum together, I use a try - catch in order to catch if they enter a decimal place. Because you cant add together 3.5 numbers you can add 3 numbers or 4. problem is if the user enters a decimal, the program will infinite loop run everything but what is in the try statement. How can i fix this?</p> <p>Here is the code for the method:</p> <pre><code>private static int requestMaxInputForFloat(Scanner scanner){ boolean appropriateAnswer = true; // assume appropriate catch not appropriate to loop again int howManyInputs = 1000000; // hold value to return how many inputs. if this value we will not run. //request an appropriate number of inputs until appropriate answer = true; do { appropriateAnswer = true; //if looped again reset value to true try{ System.out.print("How many decimal place numbers would you like to sum? "); howManyInputs = scanner.nextInt(); }catch(Exception e){ System.out.println("Sorry but you can only request to average a whole number set of data.\nTry Again."); appropriateAnswer = false; }//end of try-catch if (howManyInputs &lt;= 0) //invalid answer { System.out.println("Sorry but " + howManyInputs + " is equal to or below 0. Please try again."); }else{ appropriateAnswer = false; } }while(!appropriateAnswer);//end of while loop return howManyInputs; //return the value }// end of getMaxInput </code></pre>

    1. COadd a new line after you do `scanner.nextInt()` and run again.

    2. COIm still getting an infinite loop. even with the new line after the nextInt(); im noticing now that it is running the Try loop and printing the print(); but its as though its skipping the .nextInt(); part.

    3. COTry `scanner.nextLine()` in the `catch` block. I think the problem is that if `nextInt()` gets an error, the scanner's "pointer" is still pointing at a bad character (like the decimal point), and if you just try `nextInt()` again, it will try to scan the same bad character over again. You have to do something to make the scanner skip over it.

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.
