| Viewing runtime exceptions |
| </h1> |
| <p> |
| If an expression you evaluate causes a runtime exception, the exception will be reported in the editor. For example: |
| </p> |
| <p> |
| Type and select the expression <code>Object x = null; x.toString()</code> in the editor and click <strong>Display</strong> in the toolbar. |
| </p> |
| <p> |
| The error message: |
| </p> |
| <p> |
| <em>An exception occurred during evaluation: java.lang.NullPointerException</em> |
| </p> |
| <p> |
| will be displayed in the editor. |
