<p>Is it possible for me to pass the operation string back from when a <code>+</code>, <code>-</code> or <code>*</code> operation occurs so that it saves it as operation and then I can move on to when I press <code>=</code> or is this simply impossible?</p> <h3>Code part 1:</h3> <pre><code>public void actionPerformed(ActionEvent calculate) { JButton operand = (JButton) calculate.getSource(); String flip = operand.getLabel(); String operation = ""; System.out.println(operation); String value1 = (box1.getText()); String value2 = (box2.getText()); box1.setText(box1.getText() + operand.getLabel()); if (flip.equals("C")) { box2.setText(""); box1.setText(""); } if (flip.equals("!")) { int intValueNeg = Integer.parseInt(value1); int negateIntValue = intValueNeg * (-1); String negativeInt = Integer.toString(negateIntValue); box1.setText(negativeInt); } if (flip.equals("+")) { box2.setText(value1); box1.setText(""); operation = operand.getLabel(); } if (flip.equals("-")) { box2.setText(value1); box1.setText(""); operation = operand.getLabel(); } if (flip.equals("*")) { box2.setText(value1); box1.setText(""); operation = operand.getLabel(); } if (flip.equals("=") && operation.equals("+")) { int intValue1 = Integer.parseInt(value1); int intValue2 = Integer.parseInt(value2); int totalValue = intValue1 + intValue2; String totalResult = Integer.toString(totalValue); box1.setText(totalResult); box2.setText("0"); } if (flip.equals("=") && operation.equals("-")) { int intValue1 = Integer.parseInt(value1); int intValue2 = Integer.parseInt(value2); int totalValue = intValue2 - intValue1; String totalResult = Integer.toString(totalValue); box1.setText(totalResult); box2.setText("0"); } if (flip.equals("=") && operation.equals("*")) { int intValue1 = Integer.parseInt(value1); int intValue2 = Integer.parseInt(value2); int totalValue = intValue1 * intValue2; String totalResult = Integer.toString(totalValue); box1.setText(totalResult); box2.setText("0"); } } } </code></pre> <h3>Code part 2:</h3> <pre><code>box2 = new JTextField (10); b.add(box2); Blackbelt.add(a, BorderLayout.NORTH); Blackbelt.add(c, BorderLayout.CENTER); Blackbelt.add(b, BorderLayout.SOUTH); setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); </code></pre>

Guidance

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.
