Java Programming and Software Engineering Fundamentals

Overview

Solve real world problems with Java using multiple classes. Learn how to create programming solutions that scale using Java interfaces. Recognize that software engineering is more than writing code - it also involves logical thinking and design. By the end of this course you will have written a program that analyzes and sorts earthquake data, and developed a predictive text generator. After completing this course, you will be able to: 1. Use sorting appropriately in solving problems; 2. Develop classes that implement the Comparable interface; 3. Use timing data to analyze empirical performance; 4. Break problems into multiple classes, each with their own methods; 5. Determine if a class from the Java API can be used in solving a particular problem; 6. Implement programming solutions using multiple approaches and recognize tradeoffs; 7. Use object-oriented concepts including interfaces and abstract classes when developing programs; 8. Appropriately hide implementation decisions so they are not visible in public methods; and 9. Recognize the limitations of algorithms and Java programs in solving problems. 10. Recognize standard Java classes and idioms including exception-handling, static methods, java.net, and java.io packages.

Syllabus

Welcome to the Course

Welcome to “Java Programming: Principles of Software Design”! We are excited that you are starting our course to learn how to write programs in Java, one of the most popular programming languages in the world. In this introductory module, you will hear an overview of this course and be introduced to the supporting resources available.

Earthquakes: Programming and Interfaces

In this module, we will introduce a data set containing details about earthquakes around the world. You will learn how to pull this data into a program, search through the data, and filter the data based on desired criteria. By the end of this module, you will be able to (1) write programs that include multiple classes and ArrayLists of class types, (2) find the maximum value in an ArrayList, (3) use a Filter interface to search through data, (4) implement interfaces with method signatures, and (5) combine several filters together.

Earthquakes: Sorting Algorithms

In this module, you will continue using real earthquake data to explore several sorting algorithms. You will learn how to implement a selection sort and a bubble sort, then be introduced to a Java method Collections.sort, which sorts with much greater efficiency. By the end of this module, you will be able to (1) implement several sorting algorithms from scratch, (2) use efficient pre-existing sorting classes, (3) modify a class’s compareTo method to choose the criteria by which objects of that type are ordered, and (4) write classes that implement the Comparator interface to create interchangeable sorting criteria.

N-Grams: Predictive Text

In this module, you will explore some of the underlying concepts of predictive text. The first lesson will introduce random character generation and then how to train the character selection based on an input text. The second lesson will extend this concept to complete words. By the end of this module, you will be able to: (1) base random text generation on the frequency of characters in a training text, (2) collect a set of characters that occur in a text after randomly chosen initial character(s) to create a semi-random text, (3) extend the predictive text generation to use whole words, and (4) implement your own .equals method to compare complex data types.

Java: Tools and Libraries for Everyone

As you reach the end of this series, you may wish to extend your Java experience to tools beyond those provided here. This module will cover some of the Java basic information that is needed to program without BlueJ or the edu.duke library. After completing this module, you will be able to: (1) write a main method to start a Java program in any programming environment, (2) use the “static” keyword to modify fields, (3) find alternative editors to use with Java, (4) use exceptions to debug your program and make it more robust, and (5) reference Java libraries that are necessary to read files without the edu.duke library.

This course is a very well-designed course with meaningful projects. As a learner, nothing is more satisfying than being challenged with real-world applications and conquering the difficult projects.
In this course, the instructors take learners through basic concepts of interfaces and abstract classes, as well as introducing learners to Collections class as well as the Comparable interface in Java.

The first project is to filter a large database of earthquake occurrences, sort them out according to multiple criteria. This project familiarizes learners with how to implement interfaces and abstract classes in Java.

The second project is more challenging, implementing a Markov Model to generate random texts in different languages. This project is particularly challenging because not only learners need to persevere through the constructions of many classes and complicated methods, they also need to be very patient because the implementation uses the Random class quite often, and thus, making debugging less predictable. However, it was a very fulfilling experience being able to complete this project. After this project, I can feel comfortable moving on to intermediate Java classes.

The last project, and the most challenging, is the word-N-gram project, which also generates random texts, but to a higher level of sophistication. This is somewhat similar to a rudimentary machine learning problem: feed the program lots of training data (a long long prose like Romeo Juliet), then the machine can generate meaningful texts based on the statistics of words occurrences in the texts.

It is apparent that the Duke Course team has put in enormous effort into creating this course (and other courses in the series). They are challenging and intensive despite the friendly and fun vibe that instructors always give during their video presentations. The learning experience has been very good with all the courses in this specialization.

This is not a free course. You get a 7 day free trial, but the course is weeks long :( This review is also making me use 100 characters, LAME

Java Programming: Principles of Software Design
It is a general-purpose programming language intended to let application developers write once, run anywhere meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.
