Creating a Java Scrapbook Page
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
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 Stop the Evaluation button in the
editor toolbar), or when a System.exit() is evaluated.
There are several ways to open the
New Java Scrapbook Page

- From the menu bar, select File > New

In the File name field, type a name for the new page. The .jpage extension will be added automatically if you do not type it
Click Finish when you are done. The new scrapbook page opens in an editor.
