课程概述

How do Java programs deal with vast quantities of data? Many of the data structures and algorithms that work with introductory toy examples break when applications process real, large data sets. Efficiency is critical, but how do we achieve it, and how do we even measure it? This is an intermediate Java course. We recommend this course to learners who have previous experience in software development or a background in computer science, and in particular, we recommend that you have taken the first course in this specialization (which also requires some previous experience with Java). In this course, you will use and analyze data structures that are used in industry-level applications, such as linked lists, trees, and hashtables. You will explain how these data structures make programs more efficient and flexible. You will apply asymptotic Big-O analysis to describe the performance of algorithms and evaluate which strategy to use for efficient data retrieval, addition of new data, deletion of elements, and/or memory usage. The program you will build throughout this course allows its user to manage, manipulate and reason about large sets of textual data. This is an intermediate Java course, and we will build on your prior knowledge. This course is designed around the same video series as in our first course in this specialization, including explanations of core content, learner videos, student and engineer testimonials, and support videos -- to better allow you to choose your own path through the course!...

Great into to Java, instructors have clearly put thought in to the format with the choose your own learning style videos, and additional coverage where it may be needed. These have been very helpful.

The course curriculum is well designed and teaches students the basic data structures needed to be a successful software engineer. The project is good, and the weekly assignments are challenging.

Did not like this course at all, it is not flexible at all when it comes to IDE choices and offers very little support when it comes to using IDE's such as Intellij. The course consists of core and support videos, the idea being that if you are competent enough you are able to tackle the assignment/projects at any point. If you feel like you need more help you can dip into the support videos. The problem with this is that the videos are not actually very good and the support in the forums are lacklustre at best. The end of course peer review is an absolute joke and literally has no value to the students what so ever. It's basically students grading eachother positively so that everyone can pass lol.

Things that need to improve:

- Outdated content and Java version, Course structure needs to change, support videos need to be more supportive and maybe incorporate a code as you go approach incrementally building up on concepts, more active lecturers on the forums.

The videos are fine, but the instructions sometimes just confirm that the authors of the assignments are not very familiar with the OOP.

I am not able to upload my assignment screen prints to the course.

Environment programming is complicated to set up. I wasted a lot time just to configure the workplace.
