What is a LayoutManager?

When you add a component to an applet or a container, the container uses its layout manager to decide where to put the component. Different LayoutManager classes use different rules to place components.

java.awt.LayoutManager is an interface. Five classes in the java.awt package implement it:

• FlowLayout
• BorderLayout
• CardLayout
• GridLayout
• GridBagLayout

plus javax.swing.BoxLayout
