| 55 | |
| 56 | <ul> |
| 57 | <li> |
| 58 | Throws the given exception vA, resulting in a search for a matching handler |
| 59 | according to the usual rules of the Java programming language. |
| 60 | </li> |
| 61 | <li> |
| 62 | If no matching handler is found for the current thread, the thread |
| 63 | terminates, possibly notifying its uncaught exception handler or thread |
| 64 | group before. |
| 65 | </li> |
| 66 | </ul> |
| 67 | |
| 68 | <h2>Exceptions</h2> |
| 69 | |
| 70 | <ul> |
| 71 | <li> |
| 72 | NullPointerException if vA is null. |
| 73 | </li> |
| 74 | <li> |
| 75 | Otherwise, the indicated exception. |
