What aspects of the Java platform and its capabilities have you studied during your education?

During Java training, I studied the main features of the platform, including:

• Language syntax and object-oriented programming (classes, inheritance, interfaces).
• Working with collections and generics.
• Exception handling.
• Multithreading and synchronization.
• Working with input/output streams (I/O).
• Basics of JVM, garbage collection, and memory management.
• Using standard libraries such as java.util, java.time.
• Basics of working with databases via JDBC.
• Creating simple GUI applications using Swing.

Example of a simple class using collections and exceptions:

import java.util.ArrayList;

public class Example {
    public static void main(String[] args) {
        ArrayList<String> list = new ArrayList<>();
        list.add("Java");
        list.add("Platform");

        try {
            System.out.println(list.get(2)); // will throw an exception
        } catch (IndexOutOfBoundsException e) {
            System.out.println("Index out of bounds");
        }
    }
}
