First, we'll encode theStringinto bytes, and second, we'll decode it into a UTF-8String: StringrawString="Entwickeln Sie mit Vergnügen";ByteBufferbuffer=StandardCharsets.UTF_8.encode(rawString);Stringutf8Encode
使用Java解码UTF-8编码的String可以通过以下步骤实现: 首先,确保你已经导入了Java的java.nio.charset.StandardCharsets类。 创建一个UTF-8编码的字节数组,可以使用getBytes()方法将UTF-8编码的字符串转换为字节数组。例如:String utf8String = "你好,世界!"; byte[] utf8Bytes = utf8String.getBytes(StandardCharse...
importjava.nio.charset.StandardCharsets;importjava.util.Base64;publicclassBase64Example{publicstaticvoidmain(String[]args){Stringtext="Hello, World!";byte[]encodedBytes=Base64.getEncoder().encode(text.getBytes(StandardCharsets.UTF_8));StringencodedText=newString(encodedBytes,StandardCharsets.UTF_8);...
另外一种字符串转为UTF-8编码的方法是使用java.nio.charset.Charset和java.nio.ByteBuffer类。 Stringstr="Hello, 世界!";ByteBufferutf8Buffer=Charset.forName("UTF-8").encode(str);byte[]utf8Bytes=newbyte[utf8Buffer.remaining()];utf8Buffer.get(utf8Bytes); 1. 2. 3. 4. 上述代码中,我们首先使用...
public static String getUTF8XMLString(String xml) { // A StringBuffer Object StringBuffer sb = new StringBuffer();sb.append(xml);String xmString = "";String xmlUTF8="";try { xmString = new String(sb.toString().getBytes("UTF-8"));xmlUTF8 = URLEncoder.encode(xmString, ...
publicstaticfinalString[] ENCODES =newString[]{"UTF-8", "GBK", "GB2312", "ISO-8859-1", "ISO-8859-2"};/*** 获取字符串是什么编码,例如返回的值有:UTF-8,GBK,ISO-8859-1等 * *@paramstr *@return*/publicstaticString getEncode(String str) {byte[] data =str.getBytes();byte[] b =...

如下是一个将UTF-16转换为UTF-8编码的实现,可以看出算法比较复杂,所以性能较差,这个操作也无法使用vector API做优化。 static int encodeUTF8(char[] utf16, int off, int len, byte[] dest, int dp) { int sl = off + len, last_offset = sl - 1; while (off < sl) { char c = utf16[off...
楼上答得不对，请相信我的方法，已经确认过：String s="abc";String s1=URLEncoder.encode(s, "utf-8");String
