JOptionPane constructors

There are several versions of the JOptionPane constructor:

• public JOptionPane() -- creates a simple instance of JOptionPane.
• public JOptionPane( Object message ) -- creates a simple instance of JOptionPane containing the specified message within its message area.
• public JOptionPane( Object message, int messageType ) -- creates a simple instance of JOptionPane containing the specified message within its message area, and implementing the supplied message type.
• public JOptionPane( Object message, int messageType, int optionType ) -- creates a simple instance of JOptionPane containing the specified message within its message area and implementing the supplied message and option types.
• public JOptionPane( Object message, int messageType, int optionType, Icon icon ) -- creates a simple instance of JOptionPane containing the specified message within its message area, and implementing the supplied message and option types. The icon's parameter provides a programmer specified icon image to be displayed within the option pane.
• public JOptionPane( Object message, int messageType, int optionType, Icon icon, Object options[] ) -- creates a simple instance of JOptionPane containing the specified message within its message area and implementing the supplied message and option types. The icon's parameter provides a programmer specified icon image to be displayed within the option pane. The options array holds a list of options that will be inserted into the instance's input area.
• public JOptionPane( Object message, int messageType, int optionType, Icon icon, Object options[], Object initialValue ) -- creates a simple instance of JOptionPane containing the specified message within its message area, and implementing the supplied message and option types. The icon's parameter provides a programmer specified icon image to be displayed within the option pane. The options array holds a list of options that will be inserted into the instance's input area, and the supplied initialValue determines the list item initially selected.
