Wait for enter key to be pressed

[De8o]

I'm having a problem with the code below.

What I want to do is wait for the RETURN key to be pressed before continuing.

char listen = x;
while (listen != '\r'){
listen=keyboard.readChar(); //defined method (working)
}

does anybody have an easy way to do what I want.

Thanks in advance,
De8o

Hi De8o:

It depends directly on the implementation of the readChar() method. If you want to ignore other keys pressed, you can simply do the following:

BufferedReader d
= new BufferedReader(System.in);
try{
d.readLine();
}
catch(IOException e){}


Since the readLine method returns when the user press enter.

If you care about the other characters pressed, then yo must check the correct unicode representation of the carriage return character.

Hope it helps.
