Encode String to UTF-8

Question

I have a String with a \"ñ\" character and I have some problems with it. I need to encode this String to UTF-8 encoding. I have tried it by this way, but it doesn\'t work:

In Java7 you can use:

import static java.nio.charset.StandardCharsets.*;

byte[] ptext = myString.getBytes(ISO_8859_1); 
String value = new String(ptext, UTF_8); 

This has the advantage over getBytes(String) that it does not declare throws UnsupportedEncodingException.

If you're using an older Java version you can declare the charset constants yourself:

import java.nio.charset.Charset;

public class StandardCharsets {
    public static final Charset ISO_8859_1 = Charset.forName("ISO-8859-1");
    public static final Charset UTF_8 = Charset.forName("UTF-8");
    //....
}
