Decimal to ASCII

Hi all,

I have been writing a class method that converts a decimal value into ASCII but I am really struggling with it.

public String counterValue(int value)

so if I input 52 then the output should be '4'

if I input 48 then the output should be '0'

if I input 50 then the output should be '2'

OK, so far I have managed to do this but:

if I input 152 then I am expecting 'ÿ' but instead I see a '~' and I can't understand why.

I used (char)152 which I expected to return ÿ

Can anybody help?
