Of course, because SystemColor is a subclass of the Color class, it inherits all the members of that class,
including all the color constants that you saw in the previous section.

Creating Cursors
An object of the java.awt.Cursor class encapsulates a bitmap representation of the mouse cursor. The
Cursor class contains a range of final static constants that specify standard cursor types. You use these
to select or create a particular cursor. The standard cursor types are the following:
DEFAULT_CURSOR N_RESIZE_CURSORNE_RESIZE_CURSOR
CROSSHAIR_CURSORS_RESIZE_CURSORNW_RESIZE_CURSOR
WAIT_CURSOR

E_RESIZE_CURSORSE_RESIZE_CURSOR

TEXT_CURSOR W_RESIZE_CURSORSW_RESIZE_CURSOR

HAND_CURSOR MOVE_CURSOR

The resize cursors are the ones that you see when you resize a window by dragging its boundaries. Note
that these are not like the Color constants, which are Color objects — these constants are of type int , not
type Cursor , and are intended to be used as arguments to a Cursor constructor. To create a Cursor object
representing a text cursor you could write:
Cursor myCursor = new Cursor(Cursor.TEXT_CURSOR);

Alternatively, you can retrieve a predefined cursor using a static class method:
Cursor myCursor = Cursor.getPredefinedCursor(Cursor.TEXT_CURSOR);

This method is particularly useful when you don't want to store the Cursor object, but just want to pass
it to a method, such as setCursor() for a Component object.
If you want to see what the standard cursors look like, you could add a cursor to an application window,
along with a pink background.

TRY IT OUT: Color and Cursors
You can change the background color of the content pane for the application window and try out a dif-
ferent cursor:
