Thanks for both answers. I learnt new stuff. However, I cannot post an
example, because this is for a uni project. Let's say that I have two
methods f1 and f2, public, which return nothing. They all share the
same exception specialException. I then use

public void f1 (...) throws specialException {



public void f2 (...) throws specialException {


and the same but without any content for the signatures.

Okay, but, using this scheme, I am obliged to type twice the code to
execute once specialException has been encountered. Is it possible to
do this in another way?

Furthermore, how can I implement f1 and f2 if the only code they have
is the code which is only related to the exception they throw?


I am not sure I understand your question, but if f1 and f2 need to do
identical tests, I would put the test in its own method:

public void f1(int a) throws SpecialException {

public void f1(int b) throws SpecialException {

private void rangeCheck(int x) throws SpecialException {
   if(x < 0 || x > 100) {
     throw new SpecialException(x + " is out of range");

You can also factor out common code for the body of your catch handling:

try {
} catch (SpecialException e){
