Nicely Explained topics with good hands-on Lab exercises, Great course!
Errors so its not possible to finish the Graded Lab.
Data Structures and Algorithms
This is the third course in the Amazon Junior Software Developer Professional Certificate. In this course, you will gain a deep understanding of various fundamental data structures and algorithms essential for building efficient and scalable software solutions. Starting with Advanced Data Structures, you'll explore arrays, ArrayLists, linked lists, stacks, queues, and maps, understanding their implementations, operations, advantages, and use cases. Moving on to Searching and Sorting Algorithms, you'll manipulate essential algorithms like linear and binary search, as well as various sorting algorithms, including bubble sort, insertion sort, selection sort, merge sort, and quick sort. You will grasp the theoretical concepts and implement these algorithms in Java, gaining hands-on experience in algorithmic problem-solving. Additionally, you will be introduced to basic testing methodologies using JUnit testing, test cases, and test-driven development, ensuring the quality and reliability of your code. By the end of this course, you will be equipped with the knowledge and skills required to design efficient algorithms, manipulate complex data structures, and write robust, high-performance Java applications After completing this course, you’ll be able to: • Identify and implement basic data structures and algorithms in Java. • Analyze the efficiency and performance of data structures and algorithms in Java applications. • Identify and apply principles of recursion in Java to solve complex problems. • Implement search and sorting algorithms in Java to optimize data processing and retrieval.

I learnt very new things as a beginner but there are more topics like Trees , Graphs , more sorting and searching algorithms that are not covered , so besides it , the course is good.

评论日期：Jan 31, 2025The course topic was well structured but i'm not a fan of the presenter. it's a though course, if you are a beginner in comp-sci world then this course might not for you yet. some labs are great but the lab assignments were awful, the grading system ruin this course. this course will be better if we could do the lab assignment locally or they use pair-graded assignment for the final project. too bad there are no other professional certificate that use java in their program. if you don't really care about java or spring boot, there are better professional certificate program for you.

评论日期：Nov 6, 2025The course content is too basic, and when you have problems with the Graded Labs, technical support just redirects you to an Artificial Intelligence Assistant that does NOT help you at all.

评论日期：May 21, 2025I like it, but sometimes there were new things inside the graded labs. It's strange, because graded lab checking what you already have learn. Also there were some technical issues inside the lab / lessons, but it wasn't critical. I like test part, it helps to recharge mind

评论日期：May 17, 2025Great course! Well organized and thorough. There were some redaction errors, however, which made some instructions confusing, as well as some parts that could have been explained in a cleaner, simpler way.
