Variable Types

Three types of variables:

local variables.
instance variables.
class variables.

class MyClass {
      //This is a comment
      double salary = 45678.00; // instance variable
      static int totalcount = 0;  //class variable

      public static void main (String[] args) {
             Char male = 'm';   // local variable
      }
}

Class and instance variables are defined outside of any method.
Local variables are defined inside a method.
The scope of class and instance variables is anywhere within the class, as well as any method.
The scope of a local variable is only within the block of code in which it is defined.
Class variables are static.
