The layout manager that divides a container into regions known as north, south, east, west, and center is the BorderLayout manager in Java.

BorderLayout is a layout manager that is commonly used in Java to arrange components in five regions: north, south, east, west, and center. Each region will contain one component, and the size of the component will be determined based on the preferred size of the component and the available space in the container.

To use BorderLayout in Java, you must first import the java.awt package. Then, you need to create a new BorderLayout instance and set it as the layout manager for the desired container. You can add components to the container using the add() method, specifying which region the component should be placed in. Here is an example of how to use BorderLayout: ```java import java.awt.*; import javax.swing.*; public class BorderLayoutExample { public static void main(String[] args) { JFrame frame = new JFrame("BorderLayout Example"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(400, 300); Container container = frame.getContentPane(); container.setLayout(new BorderLayout()); container.add(new JButton("North"), BorderLayout.NORTH); container.add(new JButton("South"), BorderLayout.SOUTH); container.add(new JButton("East"), BorderLayout.EAST); container.add(new JButton("West"), BorderLayout.WEST); container.add(new JButton("Center"), BorderLayout.CENTER); frame.setVisible(true); } } ``` In this example, a JFrame is created, and a BorderLayout is set as the layout manager for the content pane. Then, five buttons are added to the different regions (north, south, east, west, and center) in the BorderLayout.
