Java gives us layout managers whose responsibility it is to determine where on the applet or application space to put the component you want to add to the GUI interface. There are five different layout managers. What are the major differences among them? Share your experiences with layout managers thus far.
Solution
The LayoutManagers are used to arrange components in a particular manner
1. BorderLayout is to arrange objects in one of five geographical locations: \"North,\"
\"South,\" \"East,\" \"West,\" and \"Center,\" possibly with some padding between. BorderLayout is the default layout for Window and
Frame objects. Because each component is associated with a direction, BorderLayout can manage at most five components; it
squashes or stretches those components to fit its constraints.
2. GridLayout arranges components into regularly spaced rows and columns. The components are arbitrarily resized to fit in the
resulting areas; their minimum and preferred sizes are consequently ignored. GridLayout is most useful for arranging very
regular, identically sized objects and for allocating space for Panels to hold other layouts in each region of the container.
3. FlowLayout is a simple layout manager that tries to arrange components with their preferred sizes, from left to right and top
to bottom in the display. A FlowLayout can have a specified justification of LEFT, CENTER, or RIGHT, and a fixed horizontal and
vertical padding. By default, a flow layout uses CENTER justification, meaning that all components are centered within the area
allotted to them. FlowLayout is the default for Panel components like Applet.
4. CardLayout is a special layout manager for creating the effect of a stack of cards. Instead of arranging all of the
container\'s components, it displays only one at a time. You would use this kind of layout to implement a hypercard stack or a
Windows-style set of configuration screens. When you add a component to the layout, you use the two-argument version of add();
the extra argument is an arbitrary string that serves as the card\'s name
5. GridBagLayout is a very flexible layout manager that allows you to position components relative to one another using
constraints. With GridBagLayout (and a fair amount of effort) you can create almost any imaginable layout. Components are
arranged at \"logical\" coordinates on a abstract grid. We\'ll call them \"logical\" coordinates because they really designate
positions in the space of rows and columns formed by the set of components. Rows and columns of the grid stretch to different
sizes, based on the sizes and constraints of the components they hold.
