Good challenges, good emphasis on relevant knowledge, but unreasoned instructions: had to rely more on myself and make my own programming exercises between some lectures to get comfortable with new material before moving on, as well as alterate some methods for better reuse during the exercises provided.

You can learn well from here, but pay attention, and dont afraid to exercise coding when you feel to

The quizzes are quite challenging. There could be more tips.

nice course with amazing resources online

need more tips for quiz of week 2

definitely not for beginners with 0 background. But it was just good on me. (make sure you know something about any kind of programming language first, or this course could be challenging )

In general a well made course. However, I do not yet see the advantage of using BlueJ over e.g. Eclipse, as most people won't work with BlueJ after the course

good 1

better course than edx

It is the best course for the beginners who want to learn java differently.

A good intro into Java. As this is Part 2 of the Specialization, I would have liked to have seen a greater introduction into more of Java's collections than just String manipulation and CSV using an apache lib.

I struggled doing the exercises

i found this course interesting. but in this you need to explain more clearly.

Good content but I wish the topics moved a little quicker. Seems like there is more hand holding than necessary.

我是一个java的初学者，我学起这个来有一定的困难。我不太推荐初学者学习这个课程。这个课程比较注重java实际运用，如果有一定java基础的话，这个课程非常适合你。

Incredibly comprehensive learning package which makes learning and skills acquisition easier. Kudos to the creators and instructors

All in all, this was a tough course, and the programming increased progressively as one moved on. Week 1 was OK, but I experienced a temporary hiccup in week 2 in the reading of the codon files; until I converted them to Strings. Even then the first file which contained only one DNA string gave its fair share of problems. In general, the section on Strings was pretty comprehensive. The programming was also pretty challenging. The section on debugging was OK, but I am at this stage still a little confused as to the amount and detail of information one is supposed to supply to someone else when you are experiencing a problem with your code. With the week 2 quiz I made a mistake than came back to haunt me in week 4; I did not read the question properly and from the outset my cgRatio method was not producing the correct answer. Eventually, after reading the specs for cgRatio again, I realised my mistake, could correct my code and get through the week 2 quiz! Week 3 on parsing, reading CSV files etc, the going was pretty good and I managed to complete the work covered in this section without too many problems. Week 4 on baby names; well, yes the mini Project was pretty extensive, with a lot of Methods being asked for and written. I found the small test files to be invaluable during testing. But the quiz contained a few curved balls. Method totalBirths does just that, and although in the specification it does say that it should also print the number of girls and boys names, and the total names in the file. Q1 and 2 tripped me up, I did not read them properly, and entered the total number of births for the girls and boys respectively. Questions 9 to 12 also resulted me in having to call a temporary halt, and write an additional method that looped over all the files from 1880 to 2014 in order to get the answers to those questions. Fortunately, method getRank came to the rescue here, doing all of the hard work!

This was a lot of work! I did "week 4" in one week, but only because I was already on leave and could focus on the mini project for the entire week. The entire course took me 6-7 weeks to complete.

I learned a lot. It was a good course, and very challenging. My greatest concern with the format you are using (80% or you don't move on - or you don't qualify), is that one can become "unstuck" as I did in week 2, but managed to get past that one.

I liked the Course, it developed my skills of thinking as a coder, but I did not like the BlueJ programming environment, as I think it required to many clicks to accomplish simple debugging tasks and didn't have user friendly interface.

phenomena of teaching is Good for logic development and practice exercise are good .

Maybe, you should let us manipulate more the file, because the dukes library is doing much. But, in general this cours was interesting !!!

Muy buen curso para comprender y mejorar las estructuras de Java

Not for beginners

Week 2 is rough, quite frankly it's just a poorly implemented mess of frustration, but if you stick with it the second half is really solid.

Good flow, but the supporting document reference are very poor. Very hard to follow. Keep simple English difficult to understand in many Quiz.

Nice course, even though the 1st week assignments are not that good, but the rest of the course I enjoyed every single minute.

Very good videos .. assignments were tough and few were confusing especially in strings .. I was challenged and got through the quiz with 100% which was satisfying
