set timeout for user’s input

by

A slightly easier way to do this than Benjamin Cox’s answer would be to do something like

int x = 2; // wait 2 seconds at most

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
long startTime = System.currentTimeMillis();
while ((System.currentTimeMillis() - startTime) < x * 1000
        && !in.ready()) {
}

if (in.ready()) {
    System.out.println("You entered: " + in.readLine());
} else {
    System.out.println("You did not enter data");
}

This will, however consume more resources than his solution.
