## 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
