| Catching Java Exceptions |
| </h1> |
| <p> |
| It is possible to suspend the execution of thread when an exception is thrown by specifying an |
| exception breakpoint. Execution can be suspended at locations where the exception is |
| uncaught, caught, or both. |
| </p> |
| <ol> |
| <li> |
| Choose <strong>Add Java Exception Breakpoint</strong> from the |
| <a href="../reference/views/breakpoints/ref-breakpoints_view.htm"><strong>Breakpoints View</strong></a> or the workbench <strong>Run</strong> menu. </li> |
| <li> |
| A dialog listing all of the available exceptions is presented (see the following figure).<br> |
| <br> |

| <br> |
| </li> |
| <li> |
| Type the name of the exception you want to catch or select it from the list. </li> |
| <li> |
| At the bottom of the page, use the checkboxes to specify how you want execution to suspend at locations where the exception is thrown. |
| <ul> |
| <li> |
| Select <strong>Caught</strong> if you want execution to suspend at locations where the exception |
| is thrown and caught by a <code>catch</code> clause. </li> |
| <li> |
| Select <strong>Uncaught</strong> if you want execution to suspend at locations where the exception is uncaught. </li> |
| </ul> |
| </li> |
| </ol> |
| <p> |
| <strong>Note:</strong> Exception breakpoints can be enabled and disabled and have hit counts |
| just like regular breakpoints. |
