Method

longreadLong(DataInputStream dataStream)
read Long 
return ((long) dataStream.read() | (long) dataStream.read() << 8 | (long) dataStream.read() << 16
        | (long) dataStream.read() << 24 | (long) dataStream.read() << 32 | (long) dataStream.read() << 40
        | (long) dataStream.read() << 48 | (long) dataStream.read() << 56);
longreadLong(DataInputStream inputStream)
Read a long value from an input stream 
return inputStream.readLong();
LongreadLong(final DataInputStream in)
read Long 
final long read = in.readLong();
return (read == Long.MIN_VALUE ? null : Long.valueOf(read));
LongreadLong(final DataInputStream in)
read Long 
if (in.readBoolean()) {
    return null;
return in.readLong();
StringreadLongString(DataInputStream in)
This is a copy of DataInputStream#readUTF(DataInput) with the main difference that the length is not read as a short but as a long. 
int utflen = (int) in.readLong();
byte[] bytearr = new byte[utflen];
char[] chararr = new char[utflen];
int c, char2, char3;
int count = 0;
int chararr_count = 0;
in.readFully(bytearr, 0, utflen);
while (count < utflen) {
