some Java confusion, help [walter savitch] [numeric types]
Q: Im trying to learn Java on my own .
Im Walter Savitchs text.
He says the following: 977 503 977 503 u0026quot; you a value of type char to a variable of type int, or any of the numeric types int follow our list of type. u0026quot;
I not get this. Is he saying that a letter to assign type int? If so, that makes no sense.

Re:Yeah, he probably should have been more clear, but I really like Savitch. I think his books are some of the best.
Are you reading the "Java: An Introduction to Computer Science & Programming" book of his?

Re:thanks for the explanation guys…
Savitch did cover it a bit later… I wish he'd covered it sooner.
but he used the example of printing the conversion of 7 from a char to an int, the result would give you 55 and not 7, because of the unicode.
honestly, your explanations were better.
thanks again.

Re:Yes, so the int takes up the numeric representation of the letter. But I believe it's the Unicode representation, not the ASCII.

Re:a letter is a character.
a character is represented by an ascii number. that is that.
so int i = 'a' is a legal argument
