For example, 1 throw new ArithmeticExeption("Divided by zero"); In the statement, the new keyword instantiates an object of class ArithmeticExeption and the string Divide by zero describes the exception. This s
In this example, the “addInteger” method does not handle the exception and throws it to the caller using the throws keyword. Therefore the caller, “main”, has to handle the IllegalArgumentException using a try-catch block. Java Throw vs Throws The table below lists the difference ...
