Graph Algorithms:
  • Breadth-First Search (BFS)

  • Depth-First Search (DFS)

  • Dijkstra's Algorithm

  • Bellman-Ford Algorithm

  • Kruskal's Algorithm

  • Prim's Algorithm


Dynamic Programming Algorithms:
  • Fibonacci Sequence

  • Longest Common Subsequence

  • Knapsack Problem


Tree Algorithms:
  • Binary Search Tree (BST) operations

  • Tree Traversal (pre-order, in-order, post-order)


String Algorithms:
  • String Matching (Naive, KMP, Rabin-Karp)

  • Longest Common Substring


Numerical Algorithms:
  • Sieve of Eratosthenes (Prime number generation)

  • Euclidean Algorithm (GCD calculation)

  • Fast Exponentiation


These are just a few examples, and there are many more algorithms that can be implemented in Java. Java provides a rich standard library, making it easier to implement and work with various algorithms. Additionally, there are also third-party libraries, such as Apache Commons Math, that offer additional algorithms and mathematical functions.


Java Algorithms refers to the implementation of various algorithms using the Java programming language. An algorithm is a step-by-step procedure or a set of rules for solving a specific problem. In the context of Java, algorithms are implemented as methods or functions that perform specific tasks efficiently. Java provides a rich set of tools and libraries that make it convenient to implement algorithms. These algorithms can be related to sorting, searching, graph traversal, dynamic programming, string manipulation, numerical computations, and more. Implementing algorithms in Java involves writing code that follows the algorithm's logic and uses the language's syntax and features. Java's standard library includes many data structures and algorithms, such as sorting and searching algorithms. For example, the java.util.Arrays class provides methods like sort() and binarySearch() for sorting and searching arrays. The java.util.Collections class offers algorithms for working with collections, including sorting and shuffling. In addition to the standard library, there are third-party libraries and frameworks available that provide a broader range of algorithms and data structures. For instance, Apache Commons Math is a popular Java library that offers numerous mathematical algorithms and functions. When implementing algorithms in Java, it's important to consider factors like time complexity, space complexity, and algorithmic efficiency. Understanding algorithmic principles and analyzing the algorithm's performance can help in choosing the most suitable algorithm for a specific problem and optimizing its implementation in Java.
