java - Read Input until control+d -

i want prompt user begin entering characters , want them able enter characters long want until hit control+d exit.

for example, can type string of numbers like: 1234567 , decide hit control+d line entered displayed (so without having hit return)

i thinking i'll need buffered reader or something. suggestions?

public class inputtest {   public static void main(string[] args) throws ioexception {     bufferedreader in = new bufferedreader(new inputstreamreader(system.in));     stringbuilder out = new stringbuilder();     while (true) {       try {         int c = in.read();         if (c != 4)  // ascii 4 04 eot (end of transmission) ctrl d, may wrong here             out.append (c);         else             break;       } catch (ioexception e) {         system.err.println ("error reading input");       }     }     system.out.println(out.tostring());   } }
