a. java.awt.Frame
b. java.awt.Window
c. java.awt.Applet
d. java.awt.Panel
Answer shown as a,b,c and d.
But in RHE (page no. 341, q.no 8)
Which of the following may contain a menu bar?

b. A frame
c. An applet
d. A menu bar
e. A menu
Answer shown as only a Frame may contain menu bar.
So, which one is correct?

Hello yojana,
The key difference between the two questions is "which can contain a menu, either as a menubar or popup menu" and "which can contain a menubar."
add( PopupMenu ) is defined in Component so Applet, Panel, Window and Frame (which have Component as a superclass) can all have PopupMenus.
setMenuBar( MenuBar ) is defined in Frame hence only Frame (and subclasses) can have a MenuBar.
Hence they're both right because they aren't asking the same thing.
Best regards,
