Working with primitive variables

“

- As with nearly all programming languages, Java supports the use of variables to store data in memory. There are two major classes of variables or data types in Java, known as primitives and objects. Primitive variables or data types are used to store numbers, individual characters and boolean values. They're stored in the fastest available memory, so you can get to the data as quickly as possible. Data type names for primitives are all in lowercase and that's how you can distinguish them from complex object data types, which always have an initial uppercase character. Most of the simple values you might store in Java code are primitives. But one data type that's absolutely not a primitive is a string. That's a complex object. All variables in Java, whether primitives or objects, must be explicitly data typed when they are declared. Java is a statically typed language and that distinguishes it from dynamic languages such as JavaScript or Python. All variables must have their types…
