以下是转换字符串为UTF-8编码的简单示例: 示例代码 importjava.nio.charset.StandardCharsets;publicclassStringToUtf8Example{publicstaticvoidmain(String[]args){StringoriginalString="hello, 你好! 😊";// 将字符串转换为UTF-8字节数组byte[]utf8Bytes=originalString.getBytes(StandardCharsets.UTF_8);// 输出...
彻底搞懂编码 GBK 和 UTF8:https://www.cnblogs.com/hehheai/p/6510879.html /*** GBK转UTF-8 *@paramgbkStr *@return*/publicstaticbyte[] getUTF8BytesFromGBKString(String gbkStr) {intn =gbkStr.length();byte[] utfBytes =newbyte[3 *n];intk = 0;for(inti = 0; i < n; i++) {int...
str = new String(str.getBytes("gbk"),"utf-8");备注说明：str.getBytes("UTF-8"); 意思是以UTF-8的编码取得字节 new String(XXX,"UTF-8"); 意思是以UTF-8的编码生成字符串 举例：public static String getUTF8XMLString(String xml) { // A StringBuffer Object StringBuffer sb = new...
String xmlUTF8="";try { xmString = new String(sb.toString().getBytes("UTF-8"));xmlUTF8 = URLEncoder.encode(xmString, "UTF-8");System.out.println("utf-8 编码：" + xmlUTF8) ;} catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace...
要将Java字符串转换为UTF编码,您需要将字符串转换为字节数组,然后将字节数组转换为UTF-8编码的字符串。以下是一个简单的示例: public class StringToUTF { public static void main(String[] args) { String originalString = "你好,世界!"; String utf8EncodedString = convertToUTF8(originalString); System....
以下是一个示例代码,将字符串从UTF-8编码转换为ISO-8859-1编码: ```java String str = "Hello, world!"; byte[] bytes = str.getBytes("UTF-8"); String result = new String(bytes, "ISO-8859-1"); System.out.println(result); ``` 在这个例子中,我们首先将字符串`str`转换为UTF-8编码的字节...
String s=new String("欲转换字符串".getBytes(),"utf-8");String s=new String("欲转换字符串".getBytes("utf-8"),"utf-8");其中 s.getBytes("UTF-8");的意思是以UTF-8的编码取得字节 new String(XXX,"UTF-8");的意思是以UTF-8的编码生成字符串 ...
StringnewStr = newString(oldStr.getBytes(), "UTF-8"); java中的String类是按照unicode进行编码的,当使用String(byte[] bytes,Stringencoding)构造字符串时,encoding所指的是bytes中的数据是按照那种方式编码的,而不是最后产生的String是什么编码方式,换句话说,是让系统把bytes中的数据由encoding编码方式转换成unic...
java中String编码转换UTF-8转GBK 1.GB2312等都可以⽤GBK代替.2.new String(row.getBytes("GB2312"), "UTF8") 这种写法是不对的, 中⽂仍然会乱码.⽅案::/** * GBK转UTF-8 * @param gbkStr * @return */ public static byte[] getUTF8BytesFromGBKString(String gbkStr) { int n = gbkStr...
