Question 13 of 95

Can we have multiple catch blocks for a single try block?

Re-explain

Yes. A single try can have several catch blocks, and Java runs the first one whose type matches the thrown exception. At most one of them runs.

try {
    // risky code
} catch (FileNotFoundException e) {
    // handle file not found
} catch (IOException e) {
    // handle other IO exceptions
} catch (Exception e) {
    // handle any other exception
}

Because the first match wins, order them from most specific to most general. The compiler enforces this. A catch for a subclass placed after a catch for its superclass could never run, so it is a compile-time error. In the example, FileNotFoundException must come before IOException, and Exception goes last.

One block can also catch several unrelated types joined with |, as in catch (IOException | SQLException e). Use this multi-catch form when the handling is the same for each type. Its parameter is implicitly final.
