Given the following java code, why is it important that the variable keyid is tested before assigning a value to the keystring variable?
private void handlekeystroke(keyevent e){
int keyid = e. getid();
string keystring
if (keyid == keyevent. key_typed) {
char c = e. getkeychar();
keystring = key character is + c;
} else {
int keycode = e. getkeycode();
keystring = key pressed is + keyevent. getkeytext( keycode);
}
