| <h1> |
| Displaying the result of evaluating an expression |
| </h1> |
| <p> |
| Displaying shows the result of evaluating an expression in the scrapbook editor. |
| </p> |
| <ol> |
| <li> |
| In the scrapbook page, either type an expression or highlight an existing expression to be displayed. For example: <code>System.getProperties();</code> |
| </li> |
| <li> |
| Click the <strong>Display</strong> button in the toolbar (or select <strong>Display</strong> from the selection's pop-up menu.) |
| </li> |
| <li> |
| The result of the evaluation appears highlighted in the scrapbook editor. The result displayed is either |
| <ul> |
| <li> |
| the value obtained by sending <code>toString()</code> to the result of the evaluation, or |
| </li> |
| <li> |
| when evaluating a primitive data type (e.g., an <em>int</em> ), the result is the simple value of the result. |
| </li> |
| </ul> |
| </li> |
| </ol> |
| <p> |
| For example: |
| </p> |
| <ul> |
| <li> |
| Type and highlight <code>new java.util.Date()</code> in the editor, and click <strong>Display</strong>. A result such as <code>(java.util.Date) Tue Jun 12 |
| 14:03:17 CDT 2001</code> appears in the editor. |
| </li> |
| <li> |
| As another example, type and highlight <code>3 + 4</code> in the editor, and press <strong>Display</strong>. The result <code>(int) 7</code> is displayed in the |
| editor. |
| </li> |
| </ul> |
