О курсе

Learn to code in Java and improve your programming and problem-solving skills. You will learn to design algorithms as well as develop and debug programs. Using custom open-source classes, you will write programs that access and transform images, websites, and other types of data. At the end of the course you will build a program that determines the popularity of different baby names in the US over time by analyzing comma separated value (CSV) files. After completing this course you will be able to: 1. Edit, compile, and run a Java program; 2. Use conditionals and loops in a Java program; 3. Use Java API documentation in writing programs. 4. Debug a Java program using the scientific method; 5. Write a Java method to solve a specific problem; 6. Develop a set of test cases as part of developing a program; 7. Create a class with multiple methods that work together to solve a problem; and 8. Use divide-and-conquer design techniques for a program that uses multiple methods....

Excellent explanations and amount of course work for practice, the tests made good use of the examples and work given, I am satisfied with what I learned in this course and see it's real world usage.

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.

The best feature of this course is that it focuses more on doing rather than mugging up definitions and technicalities of the java language. The quizzes (each one of them) require you to answer questions based on implementing the programs described in the exercise - it's a good way to get you to actually write down and code each tiny thing without ever thinking "aah this part is too easy. I can do it quickly so I won't be coding it now." This is still very much of an introductory course and does not delve much into object-oriented concepts of programming. Most concepts of Java would be discussed in further courses (I believe). So as mentioned earlier, this course mostly deals with basic programming constructs. It helps you build big programs by adding a layer of complexity each time you revisit. It's more of a programming course than a Java course. Java is just a tool used here (which is the right way to learn programming - learn the methodologies/programming paradigms rather than the language syntax). The one star it loses is because personally I was expecting a bit more object-oriented focus here rather than an intro to programming based approach. If you are new to the world of programming - by all means, do take it, you'll enjoy this one. If you're a slightly experienced person - you might consider more in-depth/challenging courses instead.

Pro-tip: Solve each exercise and code every part sincerely and you'll make the most out of it.

I took this course as part of the specialization Java Programming and Software Engineering Fundamentals. The teachers are good, but the content needs a couple of changes. The first week is a basic introduction to Object Oriented Programming: functions, methods,objects,classes. As this is just a beginners course, this is not used much for the rest of the course, only methods are really used. I think that it's unnecessary and confusing to go over these complex topics so quickly in the beginning of a course like this.

Additionally, the assignments and explanations in Week 3 and 4 are not perfectly aligned. Specifically, the videos only explain accessing folders using the DirectoryResource () or FileResource() methods, in which a prompt will appear for the user to select the file. A file name can also be specified in these methods to open a file that has already been imported to the BlueJ Project. None of the videos show how to import one or multiple files to the BlueJ Project, even tough this is required in the assignments. The assignments often request opening a file simply by giving part of its name as the user input (like "2012" in the baby names program).
