How to not display tab title in Jtabbedpane?
how to manage multiple overhand jpanel?

Answer 1

Use null for the title text when you insert the tab. For example:

JTabbedPane tabbedPane = new JTabbedPane();
tabbedPane.addTab(null, new JPanel());

Alternatively, call setTitleAt to set the title of a specific tab to null:

tabbedPane.setTitleAt(1, null);
