Do you know Java: Catch Multiple Exceptions

Catching multiple exceptions is very useful when we are intended to do the same operations when they are raised.

The feature introduced in Java 7 and by using it we can place exceptions in the same catch branch.

The old way looked like as follows.

try {

} catch (SQLException ex) {
    logger.log(ex);
} catch (RemoteException ex) {
    logger.log(ex);
} catch (NullPointerException ex) {
    logger.log(ex);
}

In Java 7 and onwards, we can place multiple exceptions in one catch branch.

try {
    // ...
} catch (SQLException | RemoteException | NullPointerException ex) {
    logger.log(ex);
} finally {
    // ...
}

Catching multiple exceptions helps us to avoid code duplications.
