Integer division by zero, on the other hand, throws because one cannot represent infinity as an int. The stack trace includes the path of execution that led to the exception method by method. ArithmeticException publicArithmeticException(Strings) Constructs an ArithmeticException with the specified detail message. By the way, I might add: Corollary: Don't throw generic exceptions. his comment is here
Throwing an exception would actually violate that standard. The reason is simply that the IEEE standard for floating point arithmetic mandates such special values whereas the quasi-standard for integer arithmetic (two's complement) has no such special values, thus leaving For example, an integer "divide by zero" throws an instance of this class. The interrupt is "read" by the operating system and forwarded to the program if a handler is registered. http://stackoverflow.com/questions/21269461/how-does-java-handle-division-by-zero

Since Java registers a handler, it receives the error and then translates it into an ArithmeticException that travels up the stack. Division By Zero Error In Teradata
In this case for example, the remote catch block could not diagnose the cause of the divide-by-zero with any certainty. Isn't that more expensive than an elevated system?

The throw point of this exception is in line 10 of method quotient. Integer arithmetic (implemented as two's complement representation by Java and most other languages and hardware) is different and has no special infinity or NaN values, thus throwing exceptions is a useful The next section demonstrates how to handle these exceptions and keep the program running successfully. This means that the JVM does not have access to the source code for where the exception occurred.
