When we run the program, we’ll see a window with the buttons arranged according to the BorderLayout rules.

We then create and add five buttons to the panel, each in a different region of the container (north, south, west, east, and center). In this example, we create a new JFrame and a JPanel and set the layout manager of the panel to BorderLayout. Panel.add(new JButton('Center'), BorderLayout.CENTER) įrame.add(panel) // add the panel to the frameįtDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) įrame.pack() // adjust the size of the frame to fit the componentsįtVisible(true) // show the frame Panel.add(new JButton('East'), BorderLayout.EAST) Panel.add(new JButton('West'), BorderLayout.WEST) Panel.add(new JButton('South'), BorderLayout.SOUTH) Panel.add(new JButton('North'), BorderLayout.NORTH) add buttons to the panel in different regions tLayout(new BorderLayout()) // create a border layout JFrame frame = new JFrame('BorderLayout Example') Let’s take a few examples to understand the layout manager in java. Although GroupLayout is a more capable and adaptable layout manager than other layout managers, it is also trickier to use. In order to regulate the size and placement of the components within the container, the developer can specify constraints for each group, which each group can contain other groups or components. Group Layout: Java 6’s GroupLayout layout manager enables programmers to specify a container’s layout by building a nested hierarchy of groups.A single component can be seen at a time, and the CardLayout can be used to switch between various views of the same data or to create an interface that looks like a wizard. Card Layout: CardLayout is a layout manager that enables switching between multiple components while keeping them in the same container by using functions like next() and previous ().Because of this, GridBagLayout is not only more capable and flexible than other layout managers but also trickier to use. Components, as opposed to GridLayout, can span multiple rows or columns and be positioned in specific places within the grid.

GridBag Layout: A layout manager called GridBagLayout arranges elements in a versatile grid of rows and columns.The layout manager is created with a specified number of rows and columns, and components are added one at a time, filling each grid cell from left to right and from top to bottom. Grid Layout: The layout manager GridLayout arranges elements in a grid of rows and columns.From left to right, the components are added, with the next component being added directly to the right of the one before it. Flow Layout: A layout manager called FlowLayout arranges components in a row, adding additional rows as needed when the width of the container is exceeded.The old component is replaced by the new one if a component is added to a region that already has one. When a component is added to the container, it is put in one of these regions and fills the entire region. Border Layout: The layout manager BorderLayout divides the container’s five regions into the north, south, east, west, and center.Java provides several built-in layout managers that can be used to arrange components within a container, which are listed below: Complex GUIs (Graphical User Interfaces) with numerous components arranged in specific ways can be made using layout managers. Regardless of the size or shape of the container, the main goal of a layout manager in java is to make sure that the components are arranged in an aesthetically pleasing and practical way. The layout manager in java takes into account the size of the container and the preferred size of the components, as well as any constraints that have been set for the layout. The class that is responsible for determining the size and position of each component within a container based on a set of rules or algorithms is called a layout manager in java. Each component’s size and placement are decided by the layout manager based on a number of variables, including the component’s preferred size, the size of the container, and any specified layout constraints. A layout manager in Java is a class that organizes elements inside a container.
