1. (TCOs 1–8) Write a class called point for the 2-D environment. Select appropriate variable(s). Write constructors. Write access methods for the variables. Write a Print method to display the variables when called. Write a test program to test it.

2. (TCOs 1–8) Write a class called square, which inheres the above point class. Select appropriate variable(s). Write constructors. Write access methods for the variables. Override the inherited print method to display variable in square and point. Write a test program to test it.

3. Start from the following code, and add Action Listener to make it functional. (Need about 10 lines) Note: 1 lb = .0.453592 kg.   import javax.swing.*; import java.awt.GridLayout; import java.awt.event.*; import java.text.DecimalFormat;   public class weightConverter extends JFrame {   public static void main(String[] args) {     JFrame frame = new weightConverter();     frame.setTitle("Weight");     frame.setSize(200, 100);     frame.setLocationRelativeTo(null);     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);     frame.setVisible(true);   }     public weightConverter() {     JLabellbllb = new JLabel("lb",SwingConstants.CENTER);     JLabellblkg = new JLabel("kg",SwingConstants.CENTER);     final JTextFieldjtflb = new JTextField();     final JTextFieldjtfkg = new JTextField();     JButtonjbtLeft = new JButton("<=");     JButtonjbtRight = new JButton("=>");       JPanel panel = new JPanel(new GridLayout(2, 3));     panel.add(lbllb);     panel.add(jbtLeft);     panel.add(lblkg);     panel.add(jtflb);     panel.add(jbtRight);     panel.add(jtfkg);       this.add(panel); // Add panel to the frame       final DecimalFormatdec = new DecimalFormat("#.00");   } } image1.jpg

4. Start from the given class, and create a NewPanel class to draw a figure like below. (Need about 15 lines) import javax.swing.*; import java.awt.Graphics; import java.awt.Color;   public class drawPerson extends JFrame {   public drawPerson() {     add(new NewPanel());   }     public static void main(String[] args) {     drawPerson frame = new drawPerson();     frame.setTitle("Person");     frame.setSize(200, 200);     frame.setLocationRelativeTo(null); // Center the frame       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);     frame.setVisible(true);      } }
