| Method | Description |
|---|---|
| equals(object obj) | It checks whether the two SocketPermission objects are equal or not. |
| getActions() | It returns the actions of this SocketPermission object in String format |

            // printing hashcode value of permission p            System.out.println(p.hashCode());Â
            // creating a permissionCollection object and            // printing it            PermissionCollection p1                = p.newPermissionCollection();            System.out.print(p1);        }        catch (Exception e) {            System.err.print("Permission denied");        }    }    public static Permission getPermission()        throws IOException    {        int port = 3000;        String host = "localhost";        return new SocketPermission(host + ":" + port,                                    "Connect,resolve");    }} |
