What arithmetic operation throws arithmetic exceptions in java?

The only arithmetic exception I can think of seeing has been caused by a division by zero statement. Trying to do integer division by 0 or mod 0 will result in this arithmetic exception. Note that floating point division by zero will result in "Infinity" being returned, and floating point modulus will result in "NaN" being returned.

It depends actually... It is not a must.

If you feel your code wouldn't throw any exception then you need not have a throws declaration in your method at all....

For instance, if a calculator program is given the command "1/0", Java can throw an ArithmeticException which could be reported back to the user.Some common types are:ArithmeticException - thrown when arithmetic error has occurred, like dividing by 0IOException - thrown when an input or output error has occurred, like a file not foundArrayIndexOutOfBoundsException - thrown when a nonexistent element of an array is requested, like arr[-1]NullPointerException - thrown when some operation if performed on an object whose value is nll.

throws keyword/statement is basically used to handle exception in java. throws keyword is used to handle "unchecked exceptions".
