| The scrapbook allows Java expressions, to be run, inspected, and displayed under the control of the debugger. Breakpoints and exceptions |
| behave as they do in a regular debug |
| session. |
| </p> |
| <p> |
| Code is edited on a scrapbook page. A VM is launched for each scrapbook page in which expressions are being evaluated. The first time an expression is evaluated in a scrapbook page after it is opened, a VM is |
| launched. The VM for a page will remain active until the page is closed, terminated explicitly (in the debugger or via the <strong>Stop the Evaluation</strong> button in the |
| editor toolbar), or when a <em>System.exit()</em> is evaluated. |
