ASCII value of char

Hello,

Here's a real rube question... I happen to want the ASCII value of a
character variable. Seriously. I've always known that Java uses
Unicode, but I also know that the Unicode values for the basic Latin
character set are the same as ASCII. But when I try to get a numeric
representation of a character, I get things like 'A' = 10 and 'a' = 10.
What I want is 'A' = 65, or 41, or something of that ilk. Is this
possible?

Thanks,
DaveO.

Yes. All you need to do is realize that char is *already* an integer,
so no conversion is necessary to get the value in most situations.

However System.out.println('A') doesn't work as expected because
println() is overloaded and will do what it *thinks* you want instead.
Still, all you need is a cast (no conversion):

System.out.println((int)'A');

So, change "rube" to "ruby slippers..."

there is nothing to do. A char IS the number.

char c = 'A';

int cp = c+1;
System.out.println( cp );

will print out 66;
