 Difference between "variable" and "field"
 ==========================================
 Field: Defined in class
 Variable: Defined in methods
   
 Eg:
   class Example{
      void firstMethod(){
        int myVar = 12;
        myField = 42;
      }
      
      int myField = 0;          P.S: field can be used before it is declared
   }
