byte[]utf8Bytes=str.getBytes("UTF-8"); 1. 这行代码使用getBytes()方法将字符串str编码为UTF-8格式的字节数组。编码格式参数被设置为"UTF-8"。 步骤3: Stringutf8Str=newString(utf8Bytes,"UTF-8"); 1. 这行代码使用String的构造函数将UTF-8格式的字节数组utf8Bytes解码为字符串utf8Str。同样,编码格...

* Convert input string to UTF-8, copies into buffer (at given offset). * 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 in...
1. byte[] bytes = "test.message".getBytes("UTF-8");//result: [116, 101, 115, 116, 46, 109, 101, 115, 115, 97, 103, 101] 2. JavaScripthas no concept of character encoding forString, everything is inUTF-16. Most of time time the value of acharinUTF-16matchesUTF-8, so yo...

在Java中,可以使用String类的构造函数或getBytes()方法来进行编码转换。下面是以UTF-8和GBK为例的编码转换过程: 将字符串从UTF-8编码转换为字节数组: String str = "编码转换"; byte[] utf8Bytes = str.getBytes("UTF-8"); 复制代码 将字节数组从UTF-8解码为字符串: String utf8Str = new String(...
public static void main(String[] args) throws IOException { Charset utf8 = StandardCharsets.UTF_8; Charset gbk2312 = Charset.forName("GB2312"); //将某段文字以gb2312编码后得到的字节数组,再以utf-8进行解码得到的文字是乱码,并且这段乱码中丢失了信息。
String srt2=new String(midbytes,"UTF-8");说明：在网络传输或其它应用中常常有同一的中间件，假设为String类型。因此需要把其它类型的数据转换为中间件的类型。将字符串进行网络传输时，如socket，需要将其在转换为byte[]类型。这中间如果采用用不同的编码可能会出现未成预料的问题，如乱码。下面举个...
如果输入是UTF8的字节用String s=new String(utf8_bytes, "UTF-8"); //utf8_bytes为byte[]类型如果输入是字符串,直接String s=原返回。 在输出是转换gb18030,不输出时不用转换。os.write(s.getBytes("GB18030")); //os为输出流 追问 PrintWriter os=new PrintWriter(new FileOutputStream("E:\\common...
