convert int to char

[chrispi]

hello everybody!

i want to alter letters like this:

char letter;
int k;
...
letter + k

for example: a+1=b, b+1=c; x+2=z;...


i did it like that:

{
...
String b;
char a,y;
int k = 1;
...
b = readWord(); // input is the letter 'A'

a = b.charAt(0);

y = a + k;

print(y);
...
}

output: 66 ('B' in ASCII) but i want the letter 'B' to be put out. how can i convert the "int" into a "char" again?

later i want to 'crypt' a whole string.

thx and nice greez



ps.: sorry for the sloppy english!
