It's a checked exception. Any checked exception will work the same. throw new InterruptedException(); } } This class Bar won't compile. As InterruptedException is a checked exception, you must either capture it (with a try-catch inside method foo()) or declare that you're throwing it (adding throws InterruptedException to the method signature ...

Checked Exception: If client can recover from an exception and would like to continue, use checked exception. Unchecked Exception: If a client can't do any thing after the exception, then raise unchecked exception. Example: If you are expected to do arithmetic operation in a method A() and based on the output from A(), you have to another ...

However, if you throw a checked exception not declared in the method signature, e.g. class QuxException extends Exception { // a different checked exception } Foo foo = mock(Foo.class); when(foo.frob()).thenThrow(QuxException.class) Mockito will fail at runtime with the somewhat misleading, generic message:

All other exception classes are checked exception classes. The Java API defines a number of exception classes, both checked and unchecked. Additional exception classes, both checked and unchecked, may be declared by programmers. You could check this via instanceof at runtime, though I don't really see where this would be useful.

Dec 23, 2012 · There are two types of exceptions: checked exceptions and unchecked exceptions. The main difference between checked and unchecked exception is that the checked exceptions are checked at compile-time while unchecked exceptions are checked at runtime.

These are exceptions that are declared on function definitions (e.g. function bob() throws ImNotBobException { ... } to say that calling that function may throw that exception - e.g. NumberFormatException when ...

Aug 13, 2011 · The only way of doing it is to extend Exception (or a subclass thereof) for a checked exception, and extending RuntimeException (or a subclass thereof) for an unchecked exception. Given how lightweight it is to do that, and the benefits you get from extending those classes, I don't think that's too onerous.

Mar 5, 2009 · With a checked exception in getRowData, this is clearly a case that's going to lead to Hejlsberg's lazy programmer simply adding empty catches. When that happens, the illegal row values will not be obvious even to the tester or the client developer debugging, rather they'll lead to knock-on errors that are hard to pinpoint the source of.

Apr 23, 2015 · Exceptions are two types in java: 1. **Checked Exception: The exceptions which are checked by compiler. For example: we you are performing operation with file, then compiler will ask you to handle IOException either by try-catch block or throws keyword. 2.
