This has probably been answered else where but how do you get the character value of an int value?
Specifically I’m reading a from a tcp stream and the readers .read() method returns an int.
How do I get a char from this?

If you’re trying to convert a stream into text, you need to be aware of which encoding you want to use. You can then either pass an array of bytes into the
Stringconstructor and provide aCharset, or useInputStreamReaderwith the appropriateCharsetinstead.Simply casting from
inttocharonly works if you want ISO-8859-1, if you’re reading bytes from a stream directly.EDIT: If you are already using a
Reader, then casting the return value ofread()tocharis the right way to go (after checking whether it’s -1 or not)… but it’s normally more efficient and convenient to callread(char[], int, int)to read a whole block of text at a time. Don’t forget to check the return value though, to see how many characters have been read.
