This document describes a Java program that creates a graphical user interface for a temperature converter. It contains the source code for a Converter class that displays labels and text fields for entering temperatures in Celsius and seeing the converted temperature in Fahrenheit. It initializes the components, lays them out using GroupLayout, and defines an action listener for the Convert button that performs the conversion calculation.

2. This is a temperature converter that I wrote in Java that has a graphical user interface.
Below is a video demonstrating the game in action and the source code is attached below that.
public class Converter extends javax.swing.JFrame {

private void initComponents() {
tempTextField = new javax.swing.JTextField();
celsiusLabel = new javax.swing.JLabel();
convertButton = new javax.swing.JButton();
fahrenheitLabel = new javax.swing.JLabel();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
setTitle("Celsius Converter");
celsiusLabel.setText("Celsius");
convertButton.setText("Convert");
convertButton.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEventevt) {
convertButtonActionPerformed(evt);
}
});
fahrenheitLabel.setText("Fahrenheit");
