A variable is a data item, because the value varies between data units in a population and can change in value over time example: age, business income, expenses, height, eye color, vehicle type for instance, income is a variable that varies between data units in a population as well as income can go up or down.

There are two kinds of types in the java programming language: primitive types and reference types ()there are, correspondingly, two kinds of data values that can be stored in variables, passed as arguments, returned by methods, and operated on: primitive values and reference values (). 37 types of research studies so far we have discussed two basic types of comparative statistical research studies: the response variable is the change found . A variable can be thought of as a container which holds value for you, during the life of a java program every variable is assigned a data type which designates the type and quantity of value it can hold instance variables are defined without the static keyword they are defined outside a method .
