DataInputStream

Constructs a new DataInputStream on the InputStream in . All reads are then filtered through this stream. Note that data read by this stream is not in a human readable format and was most likely created by a DataOutputStream.

Warning: passing a null source creates an invalid DataInputStream . All operations on such a stream will fail.

Reads up to byteCount bytes from this stream and stores them in the byte array buffer starting at byteOffset . Returns the number of bytes actually read or -1 if the end of the stream has been reached.

Equivalent to read(buffer, 0, buffer.length) .

Reads a boolean.

Reads an 8-bit byte value.

Reads a big-endian 16-bit character value.

Reads a big-endian 64-bit double value.

Reads a big-endian 32-bit float value.

Equivalent to readFully(dst, 0, dst.length); .

Reads byteCount bytes from this stream and stores them in the byte array dst starting at offset . If byteCount is zero, then this method returns without reading any bytes. Otherwise, this method blocks until byteCount bytes have been read. If insufficient bytes are available, EOFException is thrown. If an I/O error occurs, IOException is thrown. When an exception is thrown, some bytes may have been consumed from the stream and written into the array.

Reads a big-endian 32-bit integer value.

Returns a string containing the next line of text available from this stream. A line is made of zero or more characters followed by '\n' , '\r' , "\r\n" or the end of the stream. The string does not include the newline sequence.

Reads a big-endian 64-bit long value.

Reads a big-endian 16-bit short value.

Reads a string encoded with modified UTF-8 .

Reads an unsigned 8-bit byte value and returns it as an int.

Reads a big-endian 16-bit unsigned short value and returns it as an int.

Skips count number of bytes in this stream. Subsequent read() s will not return these bytes unless reset() is used. This method will not throw an EOFException if the end of the input is reached before count bytes where skipped.
