A variable basically holds a single type literal in memory through defining its type, declaring it, and setting a value to it. If you meant reference variables, they are variables which refer to the memory location of an object previously set.
An object is the actual storage space in memory in which some collection of data resides (is stored). Objects 'live' in memory spaces known as 'heaps'.
What else can I help you with?
WAP to show the difference between a variable and static variable?
difference between constant and static variables in java
Difference between reference variable and instance variable?
An object is the actual storage space in memory in which some collection of data resides.A reference variable is a variable which refers to the memory location of an object.Look at the pseudocode below:Object obj = new Object();Here obj is the reference variable, and the data to which it refers is the object.
What is the difference between instantiation and initialization in C plus plus?
Instantiation is creating the instance of the variable/object . While Initialization is to provide the variable with some value. int i; // i is an instance of an integer i=10; //initialised with the value 10
Difference between object declaration and object creation?
Declaration of the object involves only creating the reference variable to the object. Example: class SampleClass{ } Object Declaration: SampleClass obj1; Object Creation: Creating an object involves use of new keyword and actually allocating memory for that object. SampleClass obj2 = new SampleClass ();
What is the difference between roughness and flatness?
The difference between roughness and flatness is that one, flatness, is the shape of an object. Roughness is the surface or texture of an object.
What is difference between struct variable and class object?
structure variable can access the variable but class object can access the function also
What is the difference between a variable and a control?
a control is a object that cant be changed in an experiment and a variable is a object that can be changed in a expirament
What is the difference between object and variable in c?
There is no objects in C.
What is the difference between individual and a variable?
An individual is a member of the population of interest. A variable is an aspect of an individual subject or object being measured.
The difference between fixed and variable inputs?

Difference between variable resistor and rheostat?
The difference between a variable resistor and a rheostat is the same as the difference between six and half a dozen.
What the difference between a variable and control?
The difference between a controlled variable and a variable is in their state. A controlled variable is something which is rigid and constant while a variable is liable to change and inconsistent.

What is the difference between a variable being tested and a variable being controlled?
The difference between these both is that the control is what stays the same in an experiment and the variable is what changes.
What is the difference between 2N and N?
The notation 2N typically means double the amount of a variable or object N. So, 2N is twice the value of N.
What is one difference between a variable and a numerical expression?
The variable.
What is the difference between fix and variable mortgages?
The difference between fixed and variable mortgages are that in a fixed mortgage, the rate can not change. In a variable mortgage, the rate changes with time.
