This article will explain in detail how java implements character set encoding, decoding and garbled. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.
Encoding: character to byte, encode
Decoding: from bytes to characters, decode
String s = "cool"
Coding:
Byte [] data=s.getBytes (); / / Encoding
System.out.println (data.length); / / get the number of bytes
Encode to other character sets:
Data=s.getBytes ("utf8")
Decode:
Need: new String (bytes [] bytes,int offset,int length,String charsetName)
The parameters are: byte array, where to start (index), decoding length, character set mode
S=new String (data,0,data.length, "utf8") / / Decodes bytes into strings in utf8 mode
Garbled code:
1. Insufficient number of bytes (insufficient length length when decoding)
2. The character set is not uniform
This is the end of the article on "how to achieve character set encoding, decoding and garbled in java". I hope the above content can be of some help to you, so that you can learn more knowledge. if you think the article is good, please share it for more people to see.
