Foil 39 A Computational Class

From Java Tutorial - Spring 1997 Part II: Java Language and Object-Oriented Concepts Peking Tutorial, Web Certificate -- Spring-Summer 1997. by Nancy J. McCracken,Geoffrey C. Fox
A class (such as a "main routine") may also be implemented to have just one computational instance.
This application reads from standard input and counts number of characters which are then printed
class Count {
public static void main (String args[])
throws java.io.IOException
{ int count = 0;
  • while (System.in.read() != -1)
  • count++;
  • System.out.println("Input has " + count + " chars.");
}}
