    <p>I'm a first year computer science student and I'm running into some problems. We were asked to write a simple banking program using loops then asked to write the same program using methods. I'm currently stuck on changing it to a method program.</p> <p>Here is what I have for the loop program.</p> <p><pre><code>import java.util.Scanner;</p> <p>public class Prog6 { public static void main(String[] args) { Scanner stdIn = new Scanner(System.in); String act = "MUSH"; double bal = 0.0; double inc = 0.0; while (act.charAt(0) != 'Q') { System.out.print((char) 27 + "[2J"); System.out.print("## IT\'S A BANK ##\nD - Deposit\nW - Withdraw\nI - Interest\nB - Balance\nQ - Quit\n\nAction:"); act = stdIn.next(); act = act.toUpperCase(); switch (act.charAt(0)) { case 'D': System.out.print((char) 27 + "[2J"); System.out.print("Deposit how much?:"); inc = stdIn.nextDouble(); while (inc &lt; 0) { System.out.print("Deposits must be non-negative. Please try again:"); inc = stdIn.nextDouble(); } bal += inc; break; case 'W': System.out.print((char) 27 + "[2J"); System.out.print("Withdraw how much?:"); inc = stdIn.nextDouble(); while (inc &lt; 0) { System.out.print("Withdrawalas must be non-negative. Please try again:"); inc = stdIn.nextDouble(); } while (inc > bal) { System.out.print("Insufficient funds. Please try a lower amount:"); inc = stdIn.nextDouble(); } bal -= inc; break; case 'I': System.out.print((char) 27 + "[2J"); inc = bal * .04; bal += inc; System.out.print("Interest accrued: $" + inc + "; press enter key to return to menu."); stdIn.nextLine(); stdIn.nextLine(); break; case 'B': System.out.print((char) 27 + "[2J"); System.out.print("Balance = $" + bal + "; press enter key to return to menu."); stdIn.nextLine(); stdIn.nextLine(); break; case 'Q': System.out.print((char) 27 + "[2J"); break; default: System.out.print("Invalid input, try again:"); break; } } } } </pre></code> I presume that I should make a method for <code>getbalence</code>, <code>withdraw</code>, <code>deposit</code>, <code>interest</code> but it's unclear to me how I should go about this... </p> <p>I apologize if I didn't include some other information that I should have.</p> <p>I really look forward to reading your responses!</p>

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.
