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...
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(utf8Bytes, "UTF-8"); 复制代码 将字符串从GBK编码转换为字节数组: byte[] gbkBytes = str.getBytes("GBK"...
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 you ca...
