Question

In C++ I can declare a function which can not further throw exceptions as under

int myfunction (int param) throw(); // no exceptions allowed

Can I have such declaration in Java programming language?

Answer 1

No, any method can always throw an unchecked exception (RuntimeException and Error).

You only need to list checked exceptions (Exception subclasses that don’t derive from RuntimeException) in the method declaration.

And an ugly side-note: while the compiler does check that no checked exception is thrown that is not declared, you can work around that with some ugly tricks (that’s sometimes called a sneaky throw, Project Lombok supports it explicitly).
