Try/Multi-Catch vs Single Catch

Question

While adding a try/catch block in Eclipse, it gave me the option of \"Surround with try/multi-catch\" or \"Surround with try/catch.\"

This is the try/multi-catch:

Answer 1

If you want to do the same thing for all exceptions, try-multi catch and try-catch are the same, except the former is shorter. _{All programmers are lazy.}

When you want to do different thing for different exceptions:

} catch(AException e) {
    System.err.println("AException occured");
} catch(BException e) {
    System.err.println("BException occured");
}

Try-multi catch is not the right choice.

---

} catch(AException | BException e) {
    System.err.println("A or B Exception occured");
}

Note that the type of e is the nearest common supertype of AException and BException.
