        Create a 1th Tab (tab contains only headings) Tabbedpane.addtab ("Tab01", Createtextpanel ("tab 01"));

        Create a 2nd Tab (tab contains title and icon) Tabbedpane.addtab ("Tab02", New ImageIcon ("Bb.jpg"), Createtextpanel ("tab 02"); Create a 3rd Tab (tab contains title, Icon, and Tip tip) Tabbedpane.addtab ("Tab03", New ImageIcon ("Bb.jpg"), Createtextpanel ("tab 0

        }
        });

        Set the default selected tab Tabbedpane.setselectedindex (1);
