Do you use System.in.read()??

Question

As above, don't u guys find that java reading in of inputs from the command line are pretty cumbersome?

Answer 1

This is good I use it.
* Read a line of input from System.in and convert the entire line to
* a String or a number (int or a double). Kills the program on user
* error.
* @author Suzanne Menzel
* Usage: Keyboard.readLine() ==> next line of user input as a String
* Keyboard.readInt() ==> next line of user input as an int
* Keyboard.readDouble() ==> next line of user input as a double
