BorderLayout in Java Swing Example

The BorderLayout manager is one that divides a container into five regions distinct : north ( upper region ) , south ( lower region ) , west ( left region ) , east ( right region ) and center ( central region ) . Unlike managers seen previously, the order in which the components are added is irrelevant , because at the time we add the component , in which we define the region it will stay. In each region, managed to put only one component , or is, only five (5) components may be included in this layout. if an component is inserted in a region that already contains another , this will be overlapped. Likewise the grid layout, the components are resized according to the dimensions of the container.

It may be a disadvantage we can add only 5 components, but if you add a panel in each region , we have 5 panels that have their own components and their layout managers .

For defining the BorderLayout, use the following syntax: -name container.setLayout ( new BorderLayout ( horizontal – spacing , vertical – spacing ) spacing – horizontal and vertical – spacing – > optional parameters that define the space between objects .

Distribution Manager BorderLayout divides the container JPanel  into five zones, one for each component, as can be seen in Figure.
