public final int readInt() throws IOException
Returns
the next four bytes of this input stream, interpreted as an
int.
Description
Reads a signed 32-bit integer from this data input stream. This
method reads four bytes from the underlying input stream. If the
bytes read, in order, are b1, b2,
b3, and b4, where
0 <= b1, b2,
b3, b4 <= 255, then the
result is equal to:
(b1 << 24) | (b2 << 16) + (b3 << 8) +b4
This method blocks until the four bytes are read, the end of the
stream is detected, or an exception is thrown.
Exceptions
EOFException
if this input stream reaches the end before
reading four bytes.
Exceptions
IOException
if an I/O error occurs.
