Java converting keycode to string or char

Cast it to Char.

Char c=(Char)keycode;

If e is the variable parameter of the KeyEvent, use

 e.getKeyText(e.getKeyCode())

But preferably use it in a static context of KeyEvent

KeyEvent.getKeyText(e.getKeyCode())

It returns a string but you can cast to or get value of string returned in other parsable data types
