Answer 1

You could use the Character class.

Answer 2

int CharCode = (int)'a';

Or:

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

So for your example:

for (char c='A'; c <= 'Z'; c++)
{
    System.out.println(c + ": " + (int)c);
}

Answer 3

If you are interested in the unicode numbers of the letters you can do the following (here for the letter 'x'):

byte[] bytes = "x".getBytes( "UTF-16" );

System.out.println( String.format("%0" + (bytes.length * 2) + "X", 
    new BigInteger( 1, bytes )) );

This will output:

FEFF0078

For UTF-8 and other letters simply change the first line.
