What is jframe?

JFrame, Swing's top-level container provides a window on the screen and frame is a support window where additional components depend, like the menu bar, panel, label, text field, button, etc. Nearly every Swing application commences with a JFrame window. The javax.swing.JFrame class is a container that inherits the java.awt.Frame class. Moreover, JFrame operates like the main window where elements like label, button, text field are combined to create a GUI. Unlike Frame, JFrame has the choice to hide or terminate the window with the help of setDefaultCloseOperation(int) function.
