Not particularly easy, but this should work:
import java.io.ByteArrayInputStream;
import java.io.InputStreamReader;
import java.io.IOException;
import java.nio.charset.Charset;
public class Converter {
byte[] ba = new byte[1];
InputStreamReader isr;
public Converter(String csName) {
isr = new InputStreamReader(new ByteArrayInputStream(ba),
Charset.forName(csName));
}
public char convert(byte b) {
try {
isr.reset();
ba[0] = b;
return (char)isr.read();
} catch (IOException ioe) {
// This can't happen in our situation, but...
return '\0';
}
}
}
The calling program merely has to instantiate a Converter once for the
character set of interest, then call the convert method to translate the byte:
cvt = new Converter("ISO-8859-2");
...
myChar = cvt.convert(myByte);
This of course only works for 8-bit character sets.
