Multi-catch exception handling

Catch multiple exception types in a single catch block.

Code Comparison

✕ Pre-Java 7

try {
    process();
} catch (IOException e) {
    log(e);
} catch (SQLException e) {
    log(e);
} catch (ParseException e) {
    log(e);
}

✓ Java 7+

try {
    process();
} catch (IOException
    | SQLException
    | ParseException e) {
    log(e);
}

Why the modern way wins

Same handling logic written once instead of three times.

Available

Widely available since JDK 7 (July 2011)

How it works

Multi-catch handles multiple exception types with the same code. The exception variable is effectively final, so you can rethrow it without wrapping.
