It throws exception on line 4 but not on line 3.
Could anyone please explain this.

Line 4 is an int division by zero, and there is no way to represent the
result as an int, so it throws an exception.
Line 3 is a float division by zero, and there is a value,
Float.POSITIVE_INFINITY, that represents the result of dividing a
positive float by a zero float.
