Class and objects

Object Oriented Programming Concept

Class and object:

                               class Count
                                public static void main(String args[])
                                                      int count = 0;
                                                      while ( != -1)
        System.out.println("Input has " + count             +"chars.");                  

In the Java language, all methods and variables must exist within a class. So, the first line of the character-counting application defines a class, Count, that defines the methods, variables, and any other classes needed to implement the character-counting application. Since this program is such a simple one, the Count class just defines one method named main().
