Java keycode 194, what key is that?

My teacher gave me a challenge:

He told me to write a Java program which captured keys typed, and return their key code, and say what he pressed.

My problem is that he somehow typed the following sequence:

194 131 194 130 194 135

I have no idea how to reproduce this! There is no key with the code 194, and this is strange because he said he used the num-pad, but even so I can't find a way to do this. Any help?

Edit: Here is the code

public void nativeKeyPressed(NativeKeyEvent e)
{
    System.out.println(NativeKeyEvent.getKeyText(131)+" "+NativeKeyEvent.getKeyText(130)+" "+NativeKeyEvent.getKeyText(135));
    //17 = ctrl
    //18 = alt
    //113 = F2
    //32 = space
    if (!writingSupressed) ///DACA NU O BAGAT CODU ALA
    {
        if (checkCode(e.getKeyCode())) //DACA CODUL A FOST INTRODUS
        {
            new Thread(new Runnable() {
                public void run() {
                    KiraUtils.dialog("Hello, you are protected.");
                }
            }).start();
            writingSupressed=true;
            ClientMode.dm.cleanBuffer();
        }

        if (Character.isLetter((char)e.getKeyCode()))
        {
            if (isCaps)
            {
                ClientMode.dm.log(e.getKeyCode());
            }
            else
            {
                ClientMode.dm.log(e.getKeyCode()+32);
            }

        }
        else
        {
            if (e.getKeyCode()==20)
            {
                if (!capsPressed)
                {
                    capsPressed=true;
                    isCaps=!isCaps;
                    ClientMode.dm.log(20);
                }
            }
            else
            if (e.getKeyCode()==17)
            {
                if (!ctrlPressed)
                {
                    ctrlPressed=true;
                    ClientMode.dm.log(17);
                }
            }
            else if (e.getKeyCode()==16)
            {
                if (!shiftPressed)
                {
                    shiftPressed=true;
                    isCaps=!isCaps;
                    ClientMode.dm.log(16);
                }
            }
            else if (e.getKeyCode()==18)
            {
                if (!altPressed)
                {
                    altPressed=true;
                    ClientMode.dm.log(18);
                }
            }
            else
            {
                ClientMode.dm.log(e.getKeyCode());
            }
        }

    }
    else //DACA O BAGAT CODU ALA
    {
        if (checkCode(e.getKeyCode()))
        {
            new Thread(new Runnable() {
                public void run() {
                    KiraUtils.dialog("You are no longer protected.");
                }
            }).start();
            writingSupressed=false;
        }
    }
}

But pressing Alt+194 will output 18 (alt) and then the ascii codes for 1, 9 and 4
