+## Exercise 1: Click Counter Application
+
+### Description & Goal
+
+Create a simple GUI application that tracks how many times a user clicks a button and displays the count in real time. This exercise reinforces the basics of Swing components and event handling.
+
+### Code Breakdown
+
+**Part 1: Field Declarations**
+Define the UI components and a counter variable.
+
+```java
+public class ClickCounterApp extends JFrame implements ActionListener {
+    private JLabel counterLabel;    // Displays the click count
+    private JButton clickButton;    // Button to register clicks
+    private int count = 0;          // Stores the current count
+}
+```
+
+*Explanation:* We declare a `JLabel` for showing the count, a `JButton` for clicks, and an integer `count` initialized to 0.
+
+**Part 2: Constructor Setup**
+Initialize and arrange components in the window.
+
+```java
+public ClickCounterApp() {
+    setTitle("Click Counter");
+    counterLabel = new JLabel("Clicks: 0", SwingConstants.CENTER);
+    clickButton = new JButton("Click Me");
+    clickButton.addActionListener(this);
+
+    setLayout(new BorderLayout());
+    add(counterLabel, BorderLayout.CENTER);
+    add(clickButton, BorderLayout.SOUTH);
+}
+```
+
+*Explanation:* In the constructor we set the title, create the label and button, attach an `ActionListener` to the button, choose a `BorderLayout`, and place the label at center and button at bottom.
+
+**Part 3: Event Handling**
+Update count and label text when the button is clicked.
+
+```java
+@Override
+public void actionPerformed(ActionEvent e) {
+    count++;  // Increment the click counter
+    counterLabel.setText("Clicks: " + count);
+}
+```
+
+*Explanation:* The `actionPerformed` method is called on each click. We increase `count` by one and refresh the label text to reflect the new value.
+
+**Part 4: Application Entry Point**
+Launch the GUI on the Event Dispatch Thread.
+
+```java
+public static void main(String[] args) {
+    SwingUtilities.invokeLater(() -> new ClickCounterApp().setVisible(true));
+}
+```
+
+*Explanation:* Using `SwingUtilities.invokeLater` ensures thread safety by creating and showing the GUI on the Swing event thread.
