Java Data Structures Toolkit

About This Project

This repository is a collection of classic "Data Structures and Algorithms" (DSA) exercises, all grouped under the datenstrukturen package.

It includes several distinct components, each demonstrating a core Computer Science concept. The DatenStrukturen.java file acts as a main class to test and demonstrate all the other utilities.

Components Included

1. Worterbuch (Bidirectional Dictionary)

A dictionary class that provides two-way (EN <-> DE) translations.

• Core Concept: Uses two HashMaps (englishToGerman and germanToEnglish) to provide fast, O(1) lookups in both directions.
• addWord() and removeWord() methods correctly update both maps to keep them synchronized.

2. MengenOperationen (Set Theory Operations)

A static utility class that performs mathematical set operations.

• Core Concept: Demonstrates a clear understanding of java.util.Set and its built-in methods.
• getUnion(A, B): Implements A ∪ B (Birleşim) using addAll().
• getIntersection(A, B): Implements A ∩ B (Kesişim) using retainAll().
• getDifference(A, B): Implements A \ B (Fark) using removeAll().

3. ListeSortieren (List Sorter)

A class that implements a classic sorting algorithm.

• Core Concept: Demonstrates the Bubble Sort algorithm (buubleSortLis) by implementing it from scratch using nested for loops to sort a List<Integer>.
