Hi, I'm Dimitar

Web page crawling, also known as web scraping, is a powerful technique for extracting data from websites. In this tutorial, we’ll explore web page crawling using Java’s HttpClient. We’ll create a web crawler class named Crawler, which will support both synchronous and asynchronous crawling. You can configure the crawling depth,... [Read More]

In Java 11 and later, you can use the HttpClient from the standard library to fetch web page content and save it as a file. This is a powerful addition to Java, making it easier than ever to perform HTTP operations. In this blog post, we’ll explore how to achieve... [Read More]

Stacks are essential data structures in programming that follow the Last-In, First-Out (LIFO) principle, meaning that the last item added to the stack is the first one removed. Stacks are useful for managing data efficiently, such as reversing a word, evaluating expressions, or implementing undo/redo operations. In this blog post,... [Read More]

In the world of Java programming, the hashCode() method is a fundamental concept. It plays a pivotal role in hash-based data structures such as HashMaps and HashSets, ensuring efficient storage and retrieval of data. In this blog post, we’ll delve into the hashCode() method, exploring what it is and how... [Read More]

In Java, you often encounter situations where you need to compare objects. Two commonly used methods for comparison are the == operator and the equals() method. However, these two mechanisms differ significantly in their behavior. This blog post aims to clarify the differences between == and equals() through practical examples.... [Read More]

Queues are important data structures in programming that follow the First-In, First-Out (FIFO) principle, meaning that the first item added to the queue is the first one removed. Queues are useful for handling data sequentially, such as printing documents, processing requests, or simulating waiting lines. In this blog post, you... [Read More]
