| Creating a top-level class |
| </h1> |
| <p> |
| You can create classes that are not enclosed in other types. |
| </p> |
| <ol> |
| <li> |
| Open the |
| <a class="command-link" href='javascript:executeCommand("org.eclipse.ui.newWizard(newWizardId=org.eclipse.jdt.ui.wizards.NewClassCreationWizard)")'> |

| <strong>New Java Class</strong></a> wizard. |
| </li> |
| <li> |
| Edit the <strong>Source Folder</strong> field as needed to indicate in which folder you want the new class to reside. You can either type a path or |
| click the <strong>Browse</strong> button to find the folder. If a folder is found for the current selection, that folder appears in |
| the <strong>Source Folder</strong> field as the container for the new class. |
| </li> |
| <li> |
| In the <strong>Package</strong> field, type or click <strong>Browse</strong> to select the package where you want the new class |
| to reside. Leave this field empty to indicate that you want the new class to be created in the default package. |
| </li> |
| <li> |
| Leave the <strong>Enclosing type</strong> box deselected. |
| </li> |
| <li> |
| In the <strong>Name</strong> field, type a name for the new class. |
| (Optionally, in a 5.0 project, add type parameters enclosed in <strong><</strong> and <strong>></strong>). |
| </li> |
| <li> |
| Select the <strong>public</strong> or <strong>default</strong> access modifier using the <strong>Modifiers</strong> radio buttons.<br> |
| <strong>Note:</strong> The private and protected options are available only when creating a class enclosed in a type. |
| </li> |
| <li> |
| Optionally, select the <strong>abstract</strong> or <strong>final</strong> modifier for the new class using the appropriate checkboxes:<br> |
| <strong>Note:</strong> The static option is available only when creating a class enclosed in a type. |
| </li> |
| <li> |
| In the <strong>Superclass</strong> field, type or click <strong>Browse</strong> to select a superclass for the new class. |
| (Optionally, in a 5.0 project, add type arguments enclosed in <strong><</strong> and <strong>></strong>). |
| </li> |
| <li> |
| Click the <strong>Add</strong> button to add interfaces for the new class to implement. |
| (Optionally, in a 5.0 project, add type arguments enclosed in <strong><</strong> and <strong>></strong>). |
| </li> |
| <li> |
| If you want to create some method stubs in the new class: |
| <ul> |
| <li> |
| Select the <strong>public static void main(String[] args)</strong> box if you want the wizard to add the main method to the new class, thus |
| making it a starting point of an application. |
| </li> |
| <li> |
| Select the <strong>Constructors from superclass</strong> checkbox if you want the wizard to create, in the new class, a set of constructors, one |
| for each of the constructors declared in the superclass. Each of them will have the same number of parameters (of the same types) as the respective constructor from |
| the superclass. |
| </li> |
| <li> |
| Select the <strong>Inherited abstract methods</strong> checkbox if you want the wizard to generate method stubs for each of the abstract methods |
| that the new class will inherit from its superclass and implemented interfaces. |
| </li> |
| </ul> |
| </li> |
| <li> |
| Click <strong>Finish</strong> when you are done. |
| </li> |
| </ol> |
