How can we convert Strings to and from UTF8 byte arrays

Question

I have a String and I want to encode it using UT8 encoding. I want to decode the same data. How can I do this?

Answer 1

To convert STring to byte[]:

String s = "some text here";
byte[] b = s.getBytes("UTF-8");

To convert byte[] to STrings:

byte[] b = {(byte) 99, (byte)97, (byte)116};
String s = new String(b, "US-ASCII");
