Question

So the following:

char x = 88;

int number = 8 + 'E';

char x = 'a' + 8;

are legal Java operations right?

‘Cause my Java teacher’s saying that ONLY characters enclosed in single quotes are legal for char and I have a test tomorrow so I want to make sure that I’m right and that she doesn’t mark me wrong.

Also, I tried playing around with int and things like int x = 40 + 'a' and char x = 5 + 'd' and they all yield the predicted results (If I refer to the ASCII chart) without any sort of errors.

Answer 1

Yes, you could use/assign both an integer (ASCII) value or a character itself to a char variable. The same value gets assigned to the variable ultimately.

But your teacher may just be trying to suggest you a best practice, wherein using the characters rather than ASCII values is much more readable.
