Build on the software engineering skills you learned in “Java Programming: Solving Problems with Software” by learning new data structures. Use these data structures to build more complex programs that use Java’s object-oriented features. At the end of the course you will write an encryption program and a program to break your encryption algorithm.

Cryptography: Keeping Information Secret
In this module, you will learn about the basics of cryptography, the science of keeping information private and secure. You will learn about simpler cryptographic systems, which were used from the Roman Empire through the early 1900s. You will learn how to implement these ciphers, as well as how to break them. To solve these problems, you will work more with processing Strings, but also learn about arrays—a way to store an indexable sequence of elements. You will be able to: (1) combine Strings using concatenation; (2) build Strings within a Java program using StringBuilder; (3) use arrays to store and manipulate collections of data; (4) refactor your programs for improved organization using object-oriented principles; (5) and practice effective algorithm design.

GladLibs: Stories from Templates
After completing this module, you will be able (1) to program a word frequency counter to analyze any input text file, (2) to select and substitute words from a list into a document template using both ArrayList and HashMap, (3) to create new lists to use in templates, (4) to recognize brittle code, and (5) to improve code with flexible, object-oriented design. You will gain these skills in the framework of developing a randomly generated story that we call GladLibs. You may discover that bald lions change peoples’ lives, or that fluffy dinosaurs get things done in a jiffy. We hope you have fun developing your Java skills this week!

Web Server Logs: From Logs to Visits
In this module, you will learn about how web server logs store information about visitors to a website, and you will write programs to access information like user IP address, date and time of access, and more. Using Java programs you write in this module, you will be able (1) to read information from a web server log, (2) to count the number of unique visitors to your website, and (3) to count the number of times each visitor uses your website.

MiniProject: Vigenère Cipher
In this module, you will develop a program to break the Vigenère Cipher, a more complex version of the Caesar Cipher. You will improve your program in three stages: first decrypting messages where you know the language and key length, then adding the capability to handle messages with unknown key length, then extending the program to handle messages in a range of possible languages. Through this project, you will be able (1) to effectively use HashSet and HashMap, (2) to expand an algorithm from solving a simpler problem to handle broader, more complex problems, and (3) to design and modify program code involving a more complex collection of classes, methods, and data.

TOP REVIEWS FROM JAVA PROGRAMMING: ARRAYS, LISTS, AND STRUCTURED DATA
by PTNov 27, 2016
Codebreaking made the homework quite engaging, and the lectures and coursework made sense. Week3 is a little heavier than the other weeks, so bear than in mind!
by GKDec 30, 2019
The assignments were not clear and I didn't know if i should go back and use my Caesar code to get some of the answers for the assignment. it would be nice to hint a bit more

The homework is really helpful to master data structure in Java, while some of it is redundant. Learning this course takes more time than I expected, but it gives me a solid basis.

This course is challenging with quite heavy projects and exercises. However, I enjoyed it as I could learn a great deal of things about Java from this course.
