Goals

What will you learn in this course:

  1. Developing Problem-Solving Skills: The course will focus on improving your problem-solving abilities by presenting you with a variety of coding problems. You will learn how to break down complex problems into smaller, more manageable components, and devise algorithms and data structures to solve them effectively.

  2. Data Structures and Algorithms: You will learn about different data structures such as arrays, linked lists, stacks, queues, trees, graphs, and hash tables, and understand their characteristics, use cases, and implementation details. Additionally, you'll explore various algorithms like sorting, searching, and graph traversal algorithms, and learn when and how to apply them.

  3. Time and Space Complexity Analysis: You'll gain an understanding of analyzing the efficiency of algorithms and data structures in terms of time complexity (how execution time increases with the input size) and space complexity (how much memory is required). This knowledge will help you make informed decisions when choosing the most efficient solution for a given problem.

  4. Problem Solving Techniques: The course will introduce you to common problem-solving techniques such as recursion, dynamic programming, backtracking, and greedy algorithms. You'll learn when to apply each technique and how to implement them in Java.

  5. Practice with Interview Coding Problems: The course will provide you with a wide range of interview-style coding problems that frequently appear in Java developer job interviews. You'll solve these problems to reinforce your understanding of Java concepts, data structures, and algorithms, and enhance your ability to write efficient and clean code under time constraints.

  6. Code Optimization and Best Practices: The course will emphasize writing code that is not only correct but also efficient and maintainable. You'll learn about coding best practices, design patterns, and optimization techniques to improve the performance and readability of your Java code.

  7. Interview Preparation: The course will equip you with the necessary skills and knowledge to confidently tackle Java coding interviews. You'll gain experience in solving real-world coding problems, and learn how to effectively communicate your thought process and solutions during interviews.
