Classes, Objects, and Methods

• Java uses Classes, Objects, and Methods in order to perform tasks
• Classes contain the general information about the program, whereas Objects are specific instances of Classes.
• Methods are sets of instructions that tell the classes and objects what to do
• Java has a small set of Primitive Data Types which define basic data such as text and numbers
• All data types can be used as declared variables
• When an object is initialized for the first time, a Constructor is used to specify attributes
