Given the program fragment:


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

System.out.println(
    ((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?

true true true true true
false false false false false
true true false false false
true false false false false
true true false true false
true false true false true
Code will not compile or an exception will be thrown at runtime.

Explanation

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)
