如何将unicode字符打印成字符串？

Question

Getting invalid unicode error with below code

Uniocde want to print: unicode:0x16

PrintWriter pw = new PrintWriter(System.out, true);
char aa = "\u0x16";
pw.println(aa);

What's wrong happening here ?

Answer 1

\\u0x16 is not a valid unicode character reference. There should be 4 hexadecimal digits (numbers 0-9 letters af) after \\u\u003c/code> - the "x" is not valid.

If you meant to use the character U+0016, it's written as \ :

char aa = '\u0016';

The following is equivalent, but it uses an integer constant rather than a character constant.

char aa = 0x16;
