- Constructor Detail
  - Panel
```
public Panel()
```
    Creates a new panel using the default layout manager. The default layout manager for all panels is the FlowLayout class.
  - Panel
```
public Panel(LayoutManager layout)
```
    Creates a new panel with the specified layout manager.
    
    Parameters:
    
    layout - the layout manager for this panel.
    
    Since:
    
    1.1
- Method Detail
  - addNotify
```
public void addNotify()
```
    Creates the Panel's peer. The peer allows you to modify the appearance of the panel without changing its functionality.
    
    Overrides:
    
    addNotify in class Container
    
    See Also:
    
    Component.isDisplayable(), Container.removeNotify()
  - getAccessibleContext
```
public AccessibleContext getAccessibleContext()
```
    Gets the AccessibleContext associated with this Panel. For panels, the AccessibleContext takes the form of an AccessibleAWTPanel. A new AccessibleAWTPanel instance is created if necessary.
    
    Specified by:
    
    getAccessibleContext in interface Accessible
    
    Overrides:
    
    getAccessibleContext in class Component
    
    Returns:
    
    an AccessibleAWTPanel that serves as the AccessibleContext of this Panel
