Removing extra "empty" characters from byte array and converting to a string
提问by user460880
I was working on this for a while and did not find anything about this on here, so I thought I would post my solution for criticism/usefulness.
我在这方面工作了一段时间，并没有在这里找到任何关于此的信息，所以我想我会发布我的解决方案以供批评/有用。
import java.lang.*;
public class Concat
{
public static void main(String[] args)
{
byte[] buf = new byte[256];
int lastGoodChar=0;
//fill it up for example only
byte[] fillbuf=(new String("hello").getBytes());
for(int i=0;i<fillbuf.length;i++)
buf[i]=fillbuf[i];
//Now remove extra bytes from "buf"
for(int i=0;i<buf.length;i++)
{
int bint = new Byte(buf[i]).intValue();
if(bint == 0)
{
lastGoodChar = i;
break;
}
}
String bufString = new String(buf,0,lastGoodChar);
//Prove that it has been concatenated, 0 if exact match
System.out.println( bufString.compareTo("hello"));
}
}

I believe this does the same thing:
我相信这会做同样的事情：
String emptyRemoved = "he\u0000llo\u0000".replaceAll("\u0000.*", "");
