Given the program fragment:

double p = Double.POSITIVE_INFINITY;
double n = Double.NEGATIVE_INFINITY;

    ((long) p > (long) n) + " " +
    ((int) p > (int) n) + " " +
    ((short) p > (short) n) + " " +
    ((char) p > (char) n) + " " +
    ((byte) p > (byte) n));
What will be printed when this code is executed?
This example demonstrates the principle of converting real data types to integer. At first, the cast to int (or long) is performed, and then value is just truncated if we need a byte, char or short. That's why byte and short behave strangely (for example -inf -> 0x80000000 -> 0x00=0, and +inf -> 0x7FFFFFFF -> 0xFF=-1)
