Hi,
I've got a String, which charset is e.g. ISO 8859-1:

String myString;

Not really. You've got a String that consists of Unicode characters.
(UTF-16 characters, to be very precise.) All strings in Java are Unicode.
What you probalby mean is that you have a String that was initially created
from bytes that were encoded in ISO 8859-1.

and I'd like to convert it to another charset, e.g. ISO 8859-2.
How to do it?

    byte[] iso88592Bytes = myString.getBytes("ISO-8859-2");

assuming that your JRE supports 8859-2 If not, this will throw an
UnsupportedEncodingException. Here's a handy program to list all of the
encodings Java supports:

import java.util.*;
import java.nio.charset.*;

class Charsets
{
    public static void main(String[] args)
    {
        List names = new ArrayList();
        Iterator cs = Charset.availableCharsets().values().iterator() ;
        while (cs.hasNext())
        {
            names.add(((Charset)cs.next()).name());
        }
        Collections.sort(names);
        Iterator nameIter = names.iterator() ;
        while (nameIter.hasNext())
        {
            System.out.println(nameIter.next());
        }
    }
}
