Hello Friends!! I was thinking today for some examples of ArithmeticException other than devide by zero.Can anybody tell me some of such examples?

Dear friend!

Maybe I can think of some (try it out and see if they do cast the ArithmeticException you are looking for):

Math.sqrt(-1), square roots of negative numbers,
- You could create your own package for Complex numbers, and it wouldn't even be difficult, I imagine.. (but probably some university somewhere on the web has done that already, and you just need to find it..)

Divide by zero for (int) and (long) typed numbers,
I mention that again because the floating point (float), (double) types return negative infinity for -1.0/0.0, not a number (NaN) for 0.0/0.0 and positive infinity for 1.0/0.0,
besides: my compiler does allow for direct division of an integer by zero (contrary to what Ivor says in the book). Of course this throws an ArithmeticException, just like the example in the book.
- I will write my own 'alternative algebra' package (when I know Java), that handles zero multiplication and division quite differently (0: I can tell you now that I will derive it from the BigDecimal class, my dear friend :0)

What else? Eh... ArithmeticException hmmm...
1 % 0 will throw one of course, but that is effectively the same as zero division

I think I must leave you with those examples

Thanks freezotic,
for ur valuable interest that u shown in my question.The example u have given for ArithmeticException seems to work well.I really appreciate it.Thanks friend.

But I was wrong in supposing that a complex value like Math.sqrt(-1) would throw an ArithmeticException. It doesn't! Did you notice that?

In fact there is not one method in the java.lang.Math class that would throw an ArithmeticException.
Math.sqrt(-1) and other complex values are given as NaN : not a number.
The funniest is Math.round(NaN) that returns 0

Still friends?

P.S. You could throw an ArithmeticException of your own here and there, that is always possible, e.g.

if(age < 7 && number > 10)
throw new ArithmeticException("Number unsuitable for age group");

I love my Java!

I looked in the Java Language Specification and the only examples I saw were of divide by zero. Also the modulus operator(%) will throw an Arithmetic Exception if the remainder is zero. One last thing Arithmetic Exception only applies to integers and longs.
