    <p>I'm trying to calculate the payment term for the user. I try to crunch the numbers and spit them out, but that's not happening for some reason. However, it displays perfectly fine when I explicitly assign the variables a value while declaring them. </p> <pre><code>public static void creditCardPaymentCalculator() { //User Input Variables Scanner userInput = new Scanner(System.in); //User's Input double purchaseAmount, interestAmount = 0, minimumMonthlyPayment; //Table Counters int[] month = new int[12]; double payment = 0; double monthlyInterest = 0; double principal = 0; double remainingBalance = 0; double yearsOfPayment = 0; int yearCounter = 1; int monthCounter = 0; //Initialize Variables //------------------------------------------------------------------------- //Initialize Month Array for (int i = 0; i &lt; 12; i++) { month[i] = (i + 1); } //------------------------------------------------------------------------- //Welcome Message System.out.println("\n\n\n\nCredit Card Payment Calculator\n\n"); //Get User Input System.out.println("Enter Your Purchase Amount"); purchaseAmount = userInput.nextDouble(); System.out.println("Enter Interest Amount"); interestAmount = userInput.nextDouble(); System.out.println("Enter Minimum Monthly Payment"); minimumMonthlyPayment = userInput.nextDouble(); //Calculate Input For Chart (Not Working) payment = minimumMonthlyPayment; monthlyInterest = (((interestAmount / 100) * remainingBalance / yearsOfPayment) / 12); principal = payment - monthlyInterest; remainingBalance = remainingBalance - principal; //Calculate Number Of Years For Payment yearsOfPayment = (((interestAmount / 100) * remainingBalance) + remainingBalance) / minimumMonthlyPayment; //Output System.out.printf("\n Year: %d/%.0f", yearCounter, yearsOfPayment); System.out.printf("\nMonth Payment Interest Principal Remaining Balance"); System.out.printf("\n%d %.2f %.2f %.2f %.2f", month[monthCounter], payment, monthlyInterest, principal, remainingBalance); //Increment Counters monthCounter++; if (month[monthCounter] == 12) { yearCounter++; //Reset monthCounter monthCounter = 0; } //Line Spacing System.out.printf("\n\n\n\n\n"); } </code></pre>

    1. COWhat specifically does "that's not happening" mean? What part is not working for you? Expecting us to copy, paste, and run your code to even figure out what you're asking is a little inconsiderate. You already know what the issue is you're looking for help with; it's much better if you just go ahead and tell us.

    2. COThey "won'" what? :-) Please [edit](http://stackoverflow.com/posts/14838750/edit) your question and explain what the problem is that you're having, so we can try and help you solve it.

    3. COThe variables in which I calculated a value won't display any value in my printf statements. Those variables will display a value in my printf statements, however, if I initialize them as soon as they are declared. Let me know if you need another explanation.

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.
