Instance Variable Java

A variable defined in a Class, for which each object of the class has its own copy.

For example in this Class:

public class Rectangle
{
    private int width;
    private int height;

    public Rectangle(int w, int h)
    {
        width = w;
        height = h;
    }
}

width and height are instance variables. Every Rectangle object that gets constructed gets its own width and its own height.
