在这个示例中,我们使用了StandardCharsets.UTF_8来获取UTF-8字符集,并通过getBytes方法将字符串转换为字节序列。 3. (可选)将UTF-8编码的字节序列转换回String进行验证 为了验证转换的正确性,我们可以将UTF-8编码的字节序列转换回字符串。这可以通过new String(byte[] bytes, Charset charset)构造函数来实现。以下...
publicclassStringToUTF8{publicstaticvoidmain(String[]args){StringoriginalString="Hello, 你好!";try{// 使用UTF-8编码将字符串转换为字节数组byte[]utf8Bytes=originalString.getBytes("UTF-8");System.out.println("原始字符串: "+originalString);System.out.println("UTF-8字节数组: "+bytesToHex(utf8Bytes...
如果你需要将字节数组转换为InputStream,可以使用ByteArrayInputStream类: InputStreaminputStream=newByteArrayInputStream(bytes); 1. 序列图 下面是一个序列图,展示了字符串转换为UTF-8字节流的过程: ISStrDevISBytesStrDevISStrDevISBytesStrDevCreate a stringConvert to UTF-8 bytesCreate ByteArrayInputStreamUse ...
* Returns number of bytes in the string. * *Java's internal UTF8 conversion is very, very slow. * This is, rather amazingly, 8x faster than the to-string method. * Returns the number of bytes this translated into. */ public static int stringToUtf8(String s, byte[] buf, int offset...
@Test public void toObject() throws UnsupportedEncodingException{ System.out.println("2".equals(null)); String str = "ab丁亦凝";//编译环境默认是utf8格式 byte[] bytes = str.getBytes(Charset.forName("GB18030"));//这一步就是转成gb18030格式的字节码 for (byte b : bytes) { System.out....
* @return 转换后的UTF-8编码的字符串 */ public static String convertGBKtoUTF8(String gbkStr) { try { // GBK编码的字节数组 byte[] gbkBytes = gbkStr.getBytes("GBK"); // 将GBK编码的字节数组转为Java内部的Unicode字符串 String unicodeStr = new String(gbkBytes, Charset.forName("GBK")); ...
4. transform text in utf8 format to string escape()和unescape()是一对编码解码函数,一般用于URL中非ASCII字符的编码和解码 如:escape('&')返回%26 unescape('%26')返回&,都用十六进制编码 var s = '\u7cfb\u7edf\u9519\u8bef'; unescape(s) //系统错误 ...
Then, in our case, the most interesting class isStringUtils, which provides methods to encodeStrings. Using this class, getting a UTF-8 encodedStringis pretty straightforward: StringrawString="Entwickeln Sie mit Vergnügen";byte[] bytes = StringUtils.getBytesUtf8(rawString);Stringutf8EncodedString...
