The KeyEvent.getKeyCode() only for the basic letters and digits returns the ASCII code. You get 65 for A with ASCII code 65 and a with ASCII code 65+32. With !evt.isShiftDown() you can then say it was an a.

The key codes are invented by Java, so called virtual keys. The constant VK_A is haphazardly chosen to be the ASCII code of A/a.

As in ASCII A = 65 and a = 97, we see there is an offset of 97-65 = 32 between capital and lower case.

If you get Q = 81 you can add 32 to get 113 = q.

char c = (char)(evt.getKeyCode() + 32);
