An ArithmeticException is an Exception that indicates an error generated when performing a calculation.

An ArithmeticException is an Exception that indicates an error generated when performing a calculation.

A common calculation that throws this exception is trying to divide a number by zero, such as this...

double firstNumber = 10;
double secondNumber = input.readDouble();
double result = firstNumber / secondNumber;

When coding such a calculation, it is easy to overlook the fact that the user can input a zero for the secondNumber. For the vast majority of numbers, this code will run correctly, and so the programmer might overlook the potential problem.

Programmers should wrap calculation code within try-catch blocks to help catch these Exceptions, or perform validation of variables before they're used in a calculation.

ArithmeticException not thrown for overflow within 2^32

I know assigning a number greater than 2^32 has a chance to generate an ArithmeticException but today while I was programming: int x = 65535 System.out.println(x * x); Output: -131071 So no exception but an unexpected result.
