| <h1>Moving and copying Java elements</h1> |
| <p> In this section, you will use refactoring to move a resource between Java packages. |
| Refactoring actions change the structure of your code without changing its |
| semantic behavior. </p> |
| <ol> |
| <li> In the Package Explorer view, select the <em>MyTestCase.java</em> |
| file from the <em>test</em> package and drag it into the <em>junit.samples</em> package. |
| Dragging and dropping the file is similar to selecting the file and |
| choosing <strong>Refactor > Move </strong>from the context menu. |
| </li> |
| <li> You will be prompted to select whether or not to update references to the |
| file you are moving. Typically, you will want to do this to avoid compile errors. You can |
| press the <strong>Preview </strong>button to see the list of changes that |
| will be made as a result of the move. |
| </li> |
| <li> |
| <p>Press <strong>OK</strong>. The file |
| is moved, and its package declaration changes to reflect the new location.</p> |

| </p> |
| </li> |
| <li><p>Use <strong>Edit > Undo</strong> to undo the move.</p></li> |
| </ol> |
| <p>The context menu is an alternative to using drag and drop. When |
| using the menu, you must specify a target package in the Move dialog, in |
| addition to selecting the update references options you've already seen.</p> |
| <ol> |
| <li> |
| Select the <em>MyTestCase.java</em> file and from its context menu, select <strong>Refactor |
| > Move</strong>.</li> |
| <li> In the Move dialog, expand the hierarchy to browse the |
| possible new locations for the resource. Select the <em>junit.samples</em> |
| package, then click <strong>OK</strong>. The class is moved, and its |
| package declaration is updated to the new location. |
