About this course
In this course, we’re going to take a deep dive into Java classes. We’ll look at how to set the access of class variables and methods, discuss the concept of encapsulation, and write our own static methods. Then we’ll see how all Objects are related to each other through the concept of inheritance and how they can act like two different objects using polymorphism.
Skills you'll gain
Use accessor and implementor methods
Understand the concept of scope
Override methods

DNA Sequencing
The sheer size of the genome makes it difficult, if not impossible, to analyze by hand. The human genome, for example, contains 3 billion nucleotides. Thus, finding any information in the genome requires computational approaches. In this project, use Java string methods to find a protein in a strand of DNA.
