Question

Java Problrm:

Part1:
Implement the CelsiusConverter program

Part II:

Enhance your program so that can it can also convert Fahrenheit to Celsius.

You should call this version the TemperatureConverter program.

Here is CelsiusConverter program

import javax.swing.*;

import java.awt.*;

import java.awt.event.*;

public class CelsiusConverter implements ActionListener {

            JFrame frame;

            JPanel panel;

            JTextField tempCelsius;

            JLabel cLabel, fLabel;

          JButton convertTemp;

            public static void main(String[] args) {

                        CelsiusConverter converter = new CelsiusConverter();

            }

// Constructor

            public CelsiusConverter() {

                        // Create the frame and container.

                        frame = new JFrame("Convert Celsius to Fahrenheit");

                        panel = new JPanel();

                        panel.setLayout(new GridLayout(2, 2));

                      addWidgets();

                        // Add the panel to the frame.

                        frame.getContentPane().add(panel);

                        // Exit when the window is closed.

                        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

                        // Show the converter.

                        frame.pack();

                        frame.setVisible(true);

          }

// Create and add the widgets for converter.

            private void addWidgets() {

                        // Create widgets.

                        tempCelsius = new JTextField();

                        cLabel = new JLabel("Celsius");

                        convertTemp = new JButton("Convert...");

                        fLabel = new JLabel("Fahrenheit");

                      // Listen to events from Convert button.

                        convertTemp.addActionListener(this);

                        // Add widgets to container.

                      panel.add(tempCelsius);

                      panel.add(cLabel);

                        panel.add(convertTemp);

                        panel.add(fLabel);

// Implementation of ActionListener interface.

            public void actionPerformed(ActionEvent event)

            {         

                        // Convert Celsius to Fahrenheit.

            int tempFahr = (int)((Double.parseDouble(tempCelsius.getText())) * 1.8 + 32);

                        fLabel.setText(tempFahr + " Fahrenheit");

            }

}

Explanation / Answer

The explanation for my answer given above:

It is a temperature conversion program that asks the user to choose between Celsius-to-Fahrenheit conversion or Fahrenheit-to-Celsius conversion. The user will also have the option to quit the program. (You can use 1, 2, and 3 respectively).

- If the incorrect choice is typed, display an error message and prompt the user to re-enter his/her choice.
- Once the user has chosen which type of conversion he/she wants, the program should prompt the user to enter the temperature value to convert. Finally, display the converted value.

- Depending on the choice, use the following formulas accordingly:
Formula to convert from Celsius to Fahrenheit: ((9/5)*degC)+32.
Formula to convert from Fahrenheit to Celsius: 5*(degF-32)/9

- The process must continue until the user enters the option to quit the program.
- You must create two separate functions for the temperature conversion: one for the Celsius-to-Fahrenheit conversion and another one for the Fahrenheit-to-Celsius conversion.
