Introduction to Java: Objects, Methods, Classes, and Interfaces
The programming language used for developing your Android applications is Oracle's Java SE, which was created by Sun Microsystems and later acquired by Oracle. As you learned in Chapter 2, Java SE stands for Java Standard Edition, though many programmers shorten this to just "Java." Java is what is called an object-oriented programming (or “OOP”) language, which you are going to learn all about during this chapter. It is important to note that all of these Java programming concepts, components, and constructs that you will be learning during this Java primer chapter will apply equally well to both the 32-bit Android 4.4.4 OS; as well as to the 64-bit Android 5.0 OS, released in 2014; Android 6.0 released in 2015; Android 7.0, released in the fourth quarter of 2016, and Android 7.1.1, released in the first quarter of 2017.
