1.string 转 byte[]

byte[] midbytes=isoString.getBytes("UTF8"); 
 
 
 

   //为UTF8编码 
 
 
 

   byte[] isoret = srt2.getBytes("ISO-8859-1"); 
 
 
 
ISO-8859-1编码
 
 
ISO-8859-

1为单字节的编码

2.byte[]转string

String isoString = new String(bytes,"ISO-8859-1"); 
 
 
 

   String srt2=new String(midbytes,"UTF-8");
