POJava button question
text
Body
copied!<p>I am trying to get the user to input 2 fields. One is the volume of the pool and one is the volume of the hut tub. This then calculates the price of each, what I am having trouble is with if the user enters volume for the pool, then they can't enter anything for the hot tub and vise versa. This is what I have so far. Do I need to have 2 separate fields for this, or how can it be done? </p> <p>Pretty much the string errors = ""; can be removed once I figure out how to only allow them to enter one set of numbers. Here is the calculate portion, the other part of the code is just the 3 labels. </p> <pre><code>pricePanel = new JPanel(new FlowLayout()); final JRadioButton poolPrice= new JRadioButton("Pool"); final JRadioButton tubPrice = new JRadioButton("Hot Tub"); poolPrice.setSelected(true); ButtonGroup group = new ButtonGroup(); group.add(poolPrice); group.add(tubPrice); pricePanel.add(poolPrice); pricePanel.add(tubPrice); pricePanel.add(new JLabel("Enter the pool's volume: ")); final JTextField poolField = new JTextField(10); pricePanel.add(poolField); pricePanel.add(new JLabel("Enter the tub's volume: ")); final JTextField tubField = new JTextField(10); pricePanel.add(tubField); JButton calculatePrice = new JButton("Calculate Price"); calculatePrice.setMnemonic('C'); pricePanel.add(calculatePrice); pricePanel.add(createExitButton()); pricePanel.add(new JLabel("The price is:$ ")); final JTextField priceField = new JTextField(10); priceField.setEditable(false); pricePanel.add(priceField); calculatePrice.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { double pool = Double.parseDouble (poolField.getText()); double tub = Double.parseDouble(tubField.getText()); double price; if (poolPrice.isSelected()) { price = pool * 100; } else { price = tub * 75; } priceField.setText(df.format(price)); } }); }; ActionListener priceListener = new ActionListener() { public void actionPerformed(ActionEvent e) { if (e.getSource() == poolPrice) { tubLabel.setEnabled(false); tubField.setEnabled(false); messageArea.setVisible(true); } else if (e.getSource() == tubPrice) { poolLabel.setEnabled(false); poolField.setEnabled(false); messageArea.setVisible(true); } } }; poolPrice.addActionListener(priceListener); tubPrice.addActionListener(priceListener); </code></pre> <p>~~~~~~~~~~~~~~~~~~~~~~~~~~~~</p> <pre><code>hotTubsPanel = new JPanel(new FlowLayout()); final JRadioButton roundTub = new JRadioButton("Round Tub"); final JRadioButton ovalTub = new JRadioButton("Oval Tub"); roundTub.setSelected(true); ButtonGroup group = new ButtonGroup(); group.add(roundTub); group.add(ovalTub); hotTubsPanel.add(roundTub); hotTubsPanel.add(ovalTub); hotTubsPanel.add(new JLabel("Enter the tub's length: ")); final JTextField lengthField = new JTextField(10); hotTubsPanel.add(lengthField); final JLabel widthLabel = new JLabel("Enter the tub's width*: "); widthLabel.setEnabled(false); hotTubsPanel.add(widthLabel); final JTextField widthField = new JTextField(10); widthField.setEnabled(false); hotTubsPanel.add(widthField); hotTubsPanel.add(new JLabel("Enter the tub's depth: ")); final JTextField depthField = new JTextField(10); hotTubsPanel.add(depthField); JButton calculateVolume = new JButton("Calculate Volume"); calculateVolume.setMnemonic('C'); hotTubsPanel.add(calculateVolume); hotTubsPanel.add(createExitButton()); hotTubsPanel.add(new JLabel("The tub's volume is: ")); final JTextField volumeField = new JTextField(10); volumeField.setEditable(false); hotTubsPanel.add(volumeField); final JTextArea messageArea = createMessageArea(1, 25, "*Width will be set to the same value as length"); hotTubsPanel.add(messageArea); calculateVolume.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { if (roundTub.isSelected()) { widthField.setText(lengthField.getText()); } ValidationResult result = validateFields(new JTextField[] { lengthField, widthField, depthField }); String errors = ""; if (result.filled != 3) { errors += "Please fill out all fields!
