/**
* The annotated expression evaluates to an integer greater than or equal to -1. ("GTE" stands for
* ``Greater Than or Equal to''.)
*
* As an example use case, consider the definition of the read() method in java.io.InputStream:
*
*
*
* Reads the next byte of data from the input stream. The value byte is returned as an int in the range 0 to 255.
* If no byte is available because the end of the stream has been reached, the value -1 is returned.
* This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.
* A subclass must provide an implementation of this method.
*
* Returns: the next byte of data, or -1 if the end of the stream is reached.
* Throws: IOException - if an I/O error occurs.
*
* {@code public abstract @GTENegativeOne int read() throws IOException;}
