| <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 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>Finish</strong>. The file |
| is moved, and its package declaration changes to reflect the new location.</p> |

| </p> |
| </li> |
| <li> Select the <em>MyTestCase.java</em> file and drag it into the root |
| directory of the JUnit project. Once again, a dialog pops up letting the user decide to preview the changes. After you have pressed <strong>OK </strong>(or |
| <strong>Finish </strong>from the preview window), a default package is created to contain the |
| class, and the package declaration is removed to reflect the file's location |
| in the default package. |
| If you move a file to a default package the system additionally pops up a warning dialog, |
| informing the user about reference updates when moving to the default package. If you |
| don't want to see the dialog everytime you move a file to the default package, check the |
| <strong>Don't show this message again</strong> checkbox.<p> <img src="../images/qs-45.gif" width=530 height=181 alt="File moved to default package"> |
| </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. |
