2. Modify the Fahrenheit program so that it displays a button that when pressed causes theconversion calculation to take place. The user will have the option of pressing Enter inthe text field or pressing the button. Have the listener that is already defined for the textfield also listen for the button push. ### Java Program for Fahrenheit to Celsius ConversionThis Java program provides a graphical user interface for converting temperatures from Fahrenheit to Celsius. Below is a detailed breakdown of the code:```javaimport java.awt.*;import java.awt.event.*;import javax.swing.*;public class FahrenheitPanel extends JPanel { private JLabel inputLabel, outputLabel, resultLabel; private JTextField fahrenheit; // Constructor: Sets up the main GUI components. public FahrenheitPanel() { inputLabel = new JLabel ("Enter Fahrenheit temperature:"); outputLabel = new JLabel ("Temperature in Celsius: "); resultLabel = new JLabel ("--"); fahrenheit = new JTextField (5); fahrenheit.addActionListener (new TempListener()); add (inputLabel); add (fahrenheit); add (outputLabel); add (resultLabel); setPreferredSize (new Dimension(300, 75)); setBackground (Color.yellow); } // Represents an action listener for the temperature input field. private class TempListener implements ActionListener { // Performs the conversion when the enter key is pressed in the text field. public void actionPerformed (ActionEvent event) { int fahrenheitTemp, celsiusTemp; String text = fahrenheit.getText(); fahrenheitTemp = Integer.parseInt (text); celsiusTemp = (fahrenheitTemp-32) * 5/9; resultLabel.setText (Integer.toString (celsiusTemp)); } }}```### Explanation- **Imports**: The program uses `java.awt` and `javax.swing` for creating the graphical user interface and handling events.- **FahrenheitPanel Class**: - Extends `JPanel` to create a panel with input and output components. - **Components**: - `inputLabel`: Asks the user to enter a Fahrenheit temperature. - `outputLabel`: Displays the label for the Celsius result. - `resultLabel`: Shows the converted temperature in Celsius. - `fahrenheit`: A text field for user input. - **Layout**: - The panel is set to a yellow background with a preferred size of 300 x 75 pixels.- **TempListener Class**: - Implements `ActionListener` to handle text field input events. - **actionPerformed Method**: - Triggered when the user presses the enter key. ```java//***************************************************************// Fahrenheit.java Java Foundations//// Demonstrates the use of text fields.//***************************************************************import javax.swing.JFrame;public class Fahrenheit{ //----------------------------------------------------------------- // Creates and displays the temperature converter GUI. //----------------------------------------------------------------- public static void main (String[] args) { JFrame frame = new JFrame ("Fahrenheit"); frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); FahrenheitPanel panel = new FahrenheitPanel(); frame.getContentPane().add(panel); frame.pack(); frame.setVisible(true); }}```**Explanation:**This Java code snippet demonstrates a simple graphical user interface (GUI) application for converting temperatures, likely from Fahrenheit to another scale. The program utilizes the Swing framework to create a window (JFrame) and add components to it.- **Import Statement:** The `javax.swing.JFrame` is imported to utilize Java's Swing library for creating graphical window elements.- **Class Declaration:** The class `Fahrenheit` is declared as public, meaning it can be accessed from outside its package.- **Main Method:** This is the entry point of the program. The `main` method does the following: - Creates a new `JFrame` instance named "Fahrenheit". - Sets the default close operation to exit the application when the window is closed. - Creates an instance of `FahrenheitPanel`, which is presumably a custom component for handling GUI interactions related to temperature conversion. - Adds this panel to the frame’s content pane. - Packs the frame, which sizes it to fit the sub-components. - Sets the frame to be visible, allowing the user to interact with the GUI.This code can be further elaborated by defining the `FahrenheitPanel` class to specify how the conversion and display are handled.

Actually, java is a object oriented programming language. It is a platform independent.import java.awt.*;import java.awt.event.*;import javax.swing.*;public class fahrenheitpanel extends JPanel{private JLabel inputLabel, outputLabel,resultLabel;private JTextField fahrenheit;private JButton calculate;public fahrenheitpanel(){inputLabel = new JLabel("Enter Fahrenheittemperature:");outputLabel = new JLabel("Temperature in Celsius:");resultLabel = new JLabel("---");calculate=new JButton("Calculate");fahrenheit = new JTextField(5);fahrenheit.addActionListener (new TempListener());calculate.addActionListener (new TempListener());add (inputLabel);add (fahrenheit);add(calculate);add (outputLabel);add (resultLabel);setPreferredSize (new Dimension(300, 75));setBackground (Color.yellow);}private class TempListener implements ActionListener{public void actionPerformed (ActionEvent event){int fahrenheitTemp, celsiusTemp;String text = fahrenheit.getText();fahrenheitTemp = Integer.parseInt (text);celsiusTemp = (fahrenheitTemp-32) * 5/9;resultLabel.setText (Integer.toString (celsiusTemp));}}} import javax.swing.JFrame;public class fahrenheit{public static void main(String[] args){JFrame frame = new JFrame("Fahrenheit");frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);fahrenheitpanel panel = new fahrenheitpanel();frame.add(panel);frame.pack();frame.setVisible(true);}}
