| <h1> |
| Creating a nested class |
| </h1> |
| <p> |
| You can create classes that are enclosed in other types (that is, nested classes). |
| </p> |
| <ol> |
| <li> |
| Open the New Java Class wizard. |
| </li> |
| <li> |
| Edit the <strong>Source Folder</strong> field to indicate in which folder you want the new class to reside. You can either type a path or |
| click <strong>Browse</strong> 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> |
| Select the <strong>Enclosing Type</strong> check box and type the name of the enclosing type in the <strong>Enclosing Type</strong> field. You can |
| also click <strong>Browse</strong> to select the enclosing type for the new class. |
| </li> |
| <li> |
| In the <strong>Name</strong> field, type a name for the new class. |
| </li> |
| <li> |
| Select the desired modifiers by using the <strong>Modifiers</strong> radio buttons and check boxes. |
| </li> |
| <li> |
| In the <strong>Superclass</strong> field, type or click <strong>Browse</strong> to select a superclass for the new class. |
| </li> |
| <li> |
| Click the <strong>Add</strong> button to add interfaces for the new class to implement. |
| </li> |
| <li> |
| If you want to create some method stubs in the new class: |
| </li> |
| <li> |
| <ul> |
| <li> |
| Select the <strong>public static void main(String[] args)</strong> check 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> check box 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> check box 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> |
| <p> |
| <strong>Note:</strong> The new class is created in the same compilation unit as its enclosing type. |
