Things you find in a Java program:   (1) variables and (2) methods

Statements are (always) inside a method !!!

Object Oriented Programming (OOP) Languages has access modifiers to provide data encapsulation:

OOP (= a class) can restrict the access of certain members inside an object

A C language program looks like this:

  int x;                            // Global variable definition

  void func1(int x, double y)       // Function definition
  {
     ...
  }

  double func2(double a, double b)  // Function definition
  {
     ...
  }

  double y;                         // Global variable definition

  int func3(double a, int b)        // Function definition
  {
     ...
  }

C is not an Object Oriented Programming (OOP) Languages:

All global variables and all functions can be used (= accessed) by statements in any function !
