A Computational Class
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.");
- }}
