The java.lang.Math.abs method can return which of the following?
a. Negative infinity
b. Positive infinity
g. Negative zero
h. Positive zero
The method name abs is overloaded. There are versions that accept one argument of type int, long, float or double. The type of the return value is the same as the argument type. The result is positive infinity if the argument is negative infinity. The result is positive zero if the argument is negative zero. The result is NaN if the argument is NaN. If the argument is a negative integral value, then the returned value is the two's complement of the argument. The magnitude of Integer.MIN_VALUE is one greater than the magnitude of Integer.MAX_VALUE; therefore, the absolute value of Integer.MIN_VALUE exceeds the range of Integer.MAX_VALUE. Due to the limited range of type int, the two's complement of Integer.MIN_VALUE is Integer.MIN_VALUE. For that reason, the Math.abs method returns Integer.MIN_VALUE when the argument is Integer.MIN_VALUE. The negation of Short.MIN_VALUE is well within the range of type int; so Short.MIN_VALUE is never returned by the Math.abs method.

Using the Generics class above the following declarations work
Because Number both extends Number and is super of Number
Like the above I can see that the input list will work because Number extends Number. However I can't see List<? super Integer> qualifies when the process method will return List<? super Number> However, I don't get a compile error. I'm guessng that since all super classes of Number are also super classes of Integer it's ok.
This also works for the same reason as the first.
