How to add some JtextField in title bar of JFrame..?
Or if I want to add some components in Title bar of Jframe
Like there are tabs in Firefox
( although i know firefox is not made up in java competely )
You can call
JFrames. Then you can implement your own titlebar which can be e.g. a tab bar like in Firefox or Chrome. But you need to take care for widgets for closing, moving, minimizing the window.
