Java from getting started to mastering 12-borderlayout layouts

The Boundary layout manager divides the layout of a container into five locations: CENTER, EAST, WEST, North, south. This corresponds to the following: North, Lower South, Levocetirizine (WEST), right East (east), Middle (CENTER), as shown in.

Characteristics:

L can place the component in any of these five positions, if no position is specified, the default position is center.

L South and North position controls occupy one row, and the width of the control is automatically filled with the entire row. The east, west, and middle positions occupy one row; if there is no control in the eastern, Western, south, and North locations, the intermediate controls will automatically fill the entire screen. In Jaudon, West, south, and North locations where there is no control, the middle position control automatically occupies the position without the control.

Construction Method Summary
BorderLayout (): Constructs a new border layout with no spacing between components (the default spacing is 0 pixels).
BorderLayout (int hgap, int vgap): Constructs a border layout with the specified component (Hgap for horizontal spacing, vgap for vertical spacing).
Method Summary
Int	Gethgap (): Returns the horizontal spacing between components.
Int	Getvgap (): Returns the vertical spacing between components.
void	Removelayoutcomponent (Component comp): Removes the specified component from this border layout.
void	Sethgap (int hgap): Sets the horizontal spacing between components.
void	Setvgap (int vgap): Sets the vertical spacing between components.
