This is the second course in the Java as a Second Language Specialization. In this course, we'll take a look at Java data types, discuss what primitive data types are, and explain data classes. We'll also explore characters and strings and you'll add a new class in the lab. Next, we'll take a look at Java Control Structures. We'll explain IF statements, Loops, and arrays, and will discuss Switch Statements and the Java Programming Environment. After that, we'll define inheritance and explore how methods and properties are inherited in Java. We'll also discuss polymorphism and overloading functions before completing a lab and quiz. The final module discusses how all of the things we've learned in the previous lessons together will come together for our final lab. The labs in this course require you to download and install the Java environment. The instructor walks you through the installation of the environment in course 1 of this Specialization. It is recommended that you take these courses in order because the knowledge is cumulative.
