## Simple Name Changes in the AWT

> This page lists simple name changes between the 1.0 and 1.1 releases of the AWT. These name changes can be performed automatically by a script such as the `sed` script we provide. See How to Convert Code that Uses the AWT for instructions on using the `sed` script.

> The name changes listed in the following table are not valid for non-AWT code. At least one isn't even valid for all AWT code. Since the `sed` script can't tell what type of object it's affecting, you might find it making incorrect changes, which you'll generally discover when you see compilation error messages such as the following:

> >     CardWindow.java:40: Method setVisible(java.awt.Panel, java.lang.String) not
> >     found in class java.awt.CardLayout.
> >     	    ((CardLayout)cards.getLayout()).setVisible(cards,(String)arg);

> When you see such an error message, check whether the script incorrectly changed a method name. If you find the method name in the second column of the table below, look in the first column to see the method's original name. You can then edit the program by hand, changing the error-causing line to use the original name. For example, to correct the error above, you should change `setVisible` to `show` on line 40 of the `CardWindow.java` file.

> > Note: To see a complete list of deprecated AWT methods (1.0 methods no longer recommended in 1.1), see Deprecated Methods in the AWT.
