Question

I have a method is someone else’s program but I would rather write it in a more readable way. I just need to check whether my suggestion is correct or not.

Current Written As :

if (userData instanceof String && ((String) userData).compareTo(name) == 0)

Could be :

if(.... && userData.equals(name))

Thanks
