input - Java: read key from console without press enter key -


i want interrupt program when user press especific key. try code bellow, work enter key.

java.io.inputstreamreader reader = new java.io.inputstreamreader(system.in);  boolean b = false; while(!b)  {      try{         if ( reader.ready())          {              // read character , process              system.out.println("key pressed");             b = true;         }      }     catch (java.io.ioexception ioex)     {         system.out.println("io exception");     }      // edit, lets not hog cpu time      try      {          thread.sleep(50);          system.out.println("nop yet");     }      catch (interruptedexception ex)      {          // can't can we? ignoring           system.out.println("interrupted exception");     }  }

equivalent in c# (working):

    consolekeyinfo k1 = new consolekeyinfo('t', consolekey.t, false, false, false);     consolekeyinfo k = console.readkey(false);      if (k== k1)     {         environment.exit(1);     }

edit 1:

i tried threads , listners, not works too.

    public void keytyped(keyevent e)     public void keypressed(keyevent e)     public void keyreleased(keyevent e)
