+## HTML Validator
+
+### Instructions
+
+Create a class `HTMLValidator` that provides a method to validate whether a given HTML string is correctly formatted. The method should support a few basic HTML tags (`<html>`, `<body>`, `<div>`, `<p>`, `<b>`, `<i>`, `<h1>`, `<h2>`). If the HTML is valid, the method should return `true`. If the HTML is invalid, the method should return `false`.
+
+### Expected Class
+
+```java
+public class HTMLValidator {
+    public boolean validateHTML(String html) {
+        // Implementation to validate if the given HTML is correctly formatted
+    }
+}
+```
+
+### Usage
+
+Here is a possible `ExerciseRunner.java` to test your class:
+
+```java
+public class ExerciseRunner {
+    public static void main(String[] args) {
+        HTMLValidator validator = new HTMLValidator();
+
+        // Test case 1: Valid HTML
+        String html1 = "<html><body><h1>Hello, World!</h1></body></html>";
+        System.out.println("Is HTML valid? " + validator.validateHTML(html1)); // Expected output: true
+
+        // Test case 2: Invalid HTML (missing closing tag)
+        String html2 = "<html><body><h1>Hello, World!</body></html>";
+        System.out.println("Is HTML valid? " + validator.validateHTML(html2)); // Expected output: false
+
+        // Test case 3: Invalid HTML (incorrect nesting)
+        String html3 = "<html><body><h1><div>Hello, World!</h1></div></body></html>";
+        System.out.println("Is HTML valid? " + validator.validateHTML(html3)); // Expected output: false
+
+        // Test case 4: Valid HTML with multiple tags
+        String html4 = "<html><body><div><p>This is a <b>bold</b> word and this is <i>italic</i>.</p></div></body></html>";
+        System.out.println("Is HTML valid? " + validator.validateHTML(html4)); // Expected output: true
+    }
+}
+```
+
+### Expected Output
+
+```shell
+$ javac *.java -d build
+$ java -cp build ExerciseRunner
+Is HTML valid? true
+Is HTML valid? false
+Is HTML valid? false
+Is HTML valid? true
+$
+```
