public String format(String message,int len)

int message_len = message.length();
String rtn = "";
while(message!="")
{
byte[] cc = message.substring(0,1).getBytes();
int a=(int)cc[0];

if (a>127)

rtn+= message.substring(0,2);

1.int message_len = message.length; 少了个括号.
2.int a=message.substring(0,1); 这句得不到ASC码的.
我把他改成
byte[] cc = message.substring(0,1).getBytes();
int a=(int)cc[0];
