在java中将UTF-16 unicode字符转换为UTF-8

Question

当我得到JSON然后有\ u003c和\ u003e而不是<和>.我想在java中将它们转换回utf-8.任何帮助将受到高度赞赏.谢谢.

Answer 1

try {
    // Convert from Unicode to UTF-8
    String string = "\u003c";
    byte[] utf8 = string.getBytes("UTF-8");

    // Convert from UTF-8 to Unicode
    string = new String(utf8, "UTF-8");
} catch (UnsupportedEncodingException e) {
}
