char to ascii integer and back

[lucas]

hello one and all,

i am very new to java and i need to take an ascii character, say "A" or "a"
and convert it into its ascii integer code, say 65 or 97 respectively. then
i need to also go in the reverse from integer 97 to the character "a". what
is the most efficient way to do this in java.

Lucas,

The primitive Java type char represents a 2-byte Unicode character. I
believe that for ASCII values 0-255 these coincide, but you should check
with the specification.

Now you can go back and forth via casting. E.g.

System.out.println((int)'A');
System.out.println((char)65);
