There are two types of variables in Java:
• Primitives - A primitive variable can be one of eight types: char, boolean, byte, short, int, long, double, or float. Once a primitive has been declared, its primitive type can never change, although in most cases its value can change.
• Reference variables - A reference variable is used to refer to (or access) an object. A reference variable is declared to be of a specific type and that type can never be changed.
independent, dependent, controlled
Dependent and Independent variables
there are two kinds in every person.
have no variables
In scientific investigations, three key types of variables are independent variables, dependent variables, and controlled variables. The independent variable is the factor that is manipulated or changed by the researcher to observe its effect. The dependent variable is the outcome or response that is measured to assess the impact of the independent variable. Controlled variables are those that are kept constant throughout the experiment to ensure that any observed changes can be attributed solely to the independent variable.
hhgjk
independent variable,depedent variable and control variable are the 3 kinds of variables.
There are several possibilities. They can be called arguments and there are two kinds, variables and constants. Variables can have different values and constants are always the same.
independent, dependent, controlled
the three kinds of variables are independent,dependent and controlled
There are three kinds:the equations have a unique solutionthe equations have no solutionthe equations have infinitely many solutions.
The two types of variables are the CONSTANT and CONTROL.
An equation with two variables . . . seriously!An equation with one variable can be can be solved, but when there are two variables, you need two equations. This is called a system of two equations in two variables.Three equations in three variables, etc.

nominal and ordinal is wrong; those are the two types of qualitative variables. Ratio and interval are the two types of quantitative variables.
there are three kinds of variables.a variable must be a situation,condition or a factor1.change or manipulated variables.-are the variables that are being tested or changed.2.constant variables.-are the variables that you are not intended to test or study,or the variables to be kept constant.3.responding variables.-are the results of the maipulated variables.
