// This program repeatedly reads keypresses and prints them until you
// press '#'. To read a single keypress, we call the read() method on
// the StandardInput, the arguments being an array to hold the character
// typed (array c), and the number 1, to indicate that we want to read only
// one character from the keyboard. read() will return the number of
// characters read. StandardInput (of type InputStream) and StandardOutput
// (of type OutputStream) are special global variables used for reading
// characters from the keyboard and for writing characters to the screen.
