Known Language and Key Length - Java Programming: Arrays, Lists, and Structured Data
Object Oriented Programming in Java Specialization
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.

After completing this course, you will be able to:
1. Read and write data from/to files;
2. Solve problems involving data files;
3. Perform quantitative analyses of data (e.g., finding maximums, minimums, averages);
4. Store and manipulate data in an array or ArrayList;
5. Combine multiple classes to solve larger problems;
6. Use iterables and collections (including maps) in Java.

The course was pretty challenging (and occasionally frustrating) for a novice programmer, but doable. I enjoyed the course, and came away with a greater understanding of computers and programming.,The programming exercises are really interesting! They make programming much more fun to study. The lecturers are all great and the lessons are engaging. Enjoyed it greatly! Thank you Duke.
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.
