Why is the exception not triggered for division by zero here?

Question

(This is a follow up question to Why is this exception is not printed? Why is it showing an error?)

Here in the below code why is the ArithmeticException not tr

Answer 1

A division by zero throws an exception for integer values, but not for floating values. This is defined in the JLS #15.17.2:

The result of a floating-point division is determined by the rules of IEEE 754 arithmetic:
[...]

• Division of a nonzero finite value by a zero results in a signed infinity. The sign is determined by the rule stated above.

If you change the type of a and d to int, you will get an exception.
