Advanced Java Programming (AJP)

After completing Core Java, this subject introduced me to more advanced features of the Java language and the JDK. It deepened my understanding of object-oriented programming and modern Java practices.

Topics I studied

• Generics and type safety
• Collections Framework (List, Set, Map, Queue) in detail
• Exception handling best practices
• File I/O (reading and writing data)
• Multithreading and concurrency basics
• Lambda expressions and functional programming
• Streams API for data processing

My experience

The most challenging part was understanding multithreading and dealing with concurrency issues. What I found most useful were lambda expressions and streams, which make the code shorter, cleaner, and easier to maintain.

Code Example (Streams + Lambda)

import java.util.Arrays;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        List<String> names = Arrays.asList("Gordan", "Mila", "Marija", "Ivan");

        // Print names starting with 'M'
        names.stream()
             .filter(name -> name.startsWith("M"))
             .forEach(System.out::println);
    }
}
