Class Stdin

  • public class Stdin
extends java.lang.Object
    The Stdin class reads text from standard input. The class contains the same readLine method as BufferedReader and adds methods to read all the Java primitive data types with integrated error checking. It also handles EOF.

    This class is not meant to be instantiated.
