return bytes2UTF8string(a);

}

10.将字节流数据转换成整型

public static int bytes2int(byte b[]) {

int s = 0;

for (int i = 0; i < b.length; i++) {

s = s | ((b[i] & 0xff) << ((b.length – i – 1) * 8)); }

return s;

}

11.将字节流中的指定字节段转换成整型

public static int bytes2int2(byte b[],int offset,int len){ byte[] respcode=new byte[len];

for (int i=0;i<len;i++){

respcode[i]=b[offset];

offset++;

}

return bytes2int(respcode);

}
