In this example I developed code but I can not get the buttons to become exclusive to one another and can not get the final button for on-location to add the price onto the previous price, it is overriding the solution instead. Here is the assignment and the code that I have developed.

"Develop an interactive Java Swing application for Paula's Portraits, a photography studio.

Submit the following program: Develop a class named PhotoStudio based on JFrame container containing the proper Swing controls to allow a user to enter her/his name, phone number, email, and to compute the price of a photography session. The base price is $40 for an in-studio photo session with one person. The in-studio fee is $75 for a session with two or more subjects, and $95 for a session with a pet. A $90 fee is added to take photos on location instead of in the studio.

Place and use the following controls: textboxes to enter the customer name, phone number, and email. Include a set of mutually exclusive check boxes to select the portrait subject and another set for the session location. Include labels as appropriate to explain the application's functionality. Select and use a proper layout manager to enable an orderly arrangement of the controls on the JFrame. Add a "Create estimate" JButton which, when clicked, should generate the summary of the order and display in a JTextArea. The summary should include the customer information, order details (selections made), and the total calculated price of the order. Save your work in the PhotoStudio,java file."

Here is the code I have

class PhotoStudio extends javax.swing.JFrame {

int estimate;String name,phn,email; public PhotoStudio() { initComponents(); } @SuppressWarnings("unchecked") private void initComponents() { buttonGroup1 = new javax.swing.ButtonGroup(); jLabel1 = new javax.swing.JLabel(); jLabel2 = new javax.swing.JLabel(); jLabel3 = new javax.swing.JLabel(); jTextField1 = new javax.swing.JTextField(); jTextField2 = new javax.swing.JTextField(); jTextField3 = new javax.swing.JTextField(); jCheckBox1 = new javax.swing.JCheckBox(); jCheckBox2 = new javax.swing.JCheckBox(); jCheckBox3 = new javax.swing.JCheckBox(); jScrollPane1 = new javax.swing.JScrollPane(); jTextArea1 = new javax.swing.JTextArea(); jButton1 = new javax.swing.JButton(); jCheckBox4 = new javax.swing.JCheckBox(); jLabel4 = new javax.swing.JLabel(); setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE); setTitle("PhotoStudio Estimator"); jLabel1.setText("Name"); jLabel2.setText("Phone Number"); jLabel3.setText("Email"); jCheckBox1.setText("In-Studio(1 Subject)"); jCheckBox2.setText("In-Studio(2 or More Subjects)"); jCheckBox3.setText("In-Studio(with Pet)"); jTextArea1.setColumns(20); jTextArea1.setRows(5); jScrollPane1.setViewportView(jTextArea1); jButton1.setText("Create Estimate"); jButton1.addActionListener(new java.awt.event.ActionListener() { public void actionPerformed(java.awt.event.ActionEvent evt) { jButton1ActionPerformed(evt); } });

jCheckBox4.setText("On-Location"); jLabel4.setFont(new java.awt.Font("Arial", 1, 18)); // NOI18N jLabel4.setText("PhotoStudio Estimator");
