Sorting Algorithms

This section explores standard algorithms frequently used to solve various programming problems, with a focus on array sorting algorithms implemented in Java.

There are many sorting algorithms and their variations. Some of the most well-known types include: Bubble Sort, Selection Sort, Insertion Sort, Radix Sort, Quick Sort, Heap Sort, Merge Sort, Shell Sort, Topological Sort, and Composite Key Quick Sort. In this tutorial series, we will cover the most popular and commonly used Java sorting techniques.

Each sorting algorithm has its own use cases, performance characteristics, and time complexity. For example:

• Bubble Sort – Simple, but inefficient on large datasets (O(n²)).
• Selection Sort – Selects the smallest/largest element per iteration (O(n²)).
• Insertion Sort – Efficient for small or nearly sorted data (O(n²)).
• Merge Sort – Divide and conquer approach, good for large datasets (O(n log n)).
• Quick Sort – One of the fastest in practice for unsorted arrays (average O(n log n)).

In the following pages, you’ll find practical implementations and Java code examples for each of these algorithms.

Understanding these sorting techniques is essential for mastering data structures and algorithms in Java. These skills are frequently tested in job interviews, competitive programming, and performance-critical applications.
