How to detect End of file

Hi everyone,

I have difficulties detecting the EOF when I press ctrl-D at the netbeans output window.

Here is the code I am using for detecting eof when pressing ctrl-D:

def main(args: Array[String]) = {
    var line:String = ""
    do{
        line = readLine()
        println(line)
    }while(line != null)
  }

When using Ctrl + D, the loop doesn't end and the code that follows the loop is not executed.

thank you,

Francisco Perez

I don't use netbeans, but why do you expect Ctrl-D to send an EOF? Does Netbeans do that for Java? Or is that what happens in a linux shell? (For windows command prompt it's Ctrl-Z)

Hi,
NetBeans uses GNU compilers and environment and in the GNU world Ctrl+Z stops the application, while end of stream is Ctrl+D.

I don't know for a fact but I'd be very surprised if its Swing GUI worked that way. What makes you say that it uses GNU compilers/environment?

In any case, try running your app in a real terminal and see if it behaves. If it does you'll know that netbeans is the "culprit," and if not then you know you have a problem with your code.

The code works as expected in a terminal. Ctrl-D ends the stream and the loop.

Then i will just execute my code with the linux terminal and forget about netbeans. 
Thank you very much everyone for your help.
