Syntax

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.
