Question

Is it possible to initialize a String from an array of hex values, like C style?

unsigned char[] charArray = {0x41, 0x42, 0x43};

Why is not possible to do something like this?

String charArray = new String((byte[]) {0x41, 0x42, 0x43});

Answer 1

It is perfectly possible, you can do it in several ways.

• Using unicode escapes:

  String string = "\u0041\u0042\u0043";
  

• Creating and using a byte array:

  String string = new String(new byte[] {(byte) 0x41, (byte) 0x42, (byte) 0x43});
  

The main thing you have to remember is that the string is not an array of something, it is a separate object. Therefore it should either be created as a string literal, or with one of the constructors.
