Re: [Java] Keyboard input

 

Simple code for test purpose... do not try this at home... or try at your
own risk... hehehehehehe

*import *java.io.IOException;

*public class *MainClass {

*public static **void *main(String[] args) {

*try *{
*while *(*true*) {
*int *datum = *System.in.read**()*;
*if *(datum == -1)
*break*;
System.out.println(datum);
}
} *catch *(IOException ex) {
System.err.println("Couldn't read from System.in!");
}
}
}
