Joptionpane dialog box

The static factory method of the Joptionpane class primarily creates 4 types of dialog boxes

&1 showmessagedialog----Display a modal dialog box with OK button (only the currently popup dialog is executed)

JAVA instance:

Joptionpane.showmessagedialog (JL, "Welcome to our Store", "Dialog's title", Joptionpane.information_message);

&2 Showoptiondialog-----This function can change the text displayed on the button, and you can customize the options

Java instance:

Object [] options = {"Lily", "White Rose", "Little Daisy", "Yellow Rose"};

int index = Joptionpane.showoptiondialog (JP, "What flowers do you like?") "," dialog box title ", Joptionpane.yes_no_cancel_option,joptionpane.question_message,null,options,options[3]);

&3 Showconfirmdialog----This function uses only two options yes/no

Java instance:

int n = joptionpane.showconfirmdialog (JL, "Did you have a good last?") "," dialog box title ", Joptionpane.yes_no_option,joptionpane.question_message);

&4 Showinputdialog-----This function is used to add content directly to a text box

Joptionpane.showinputdialog (JL, "Please enter the dish you most want to eat:", "dialog title", Joptionpane.plain_message);

Attention:

The question_message and so on here are used to establish an icon from the pluggable appearance, usage: joptiondialog.question_message

Constant name Purpose

Error_message for error messages

Information_message for informational messages

Warning_message for warning messages

Plain_message for any information

Question_message for problem information

In particular, the constants in the Joptiondialog class that represent option types are as follows, usage: joptiondialog.yes_no_option

Constant name Purpose

Default_option does not provide any options

Yes_no_option yes,no Options

Yes_no_cancel_option yes,no,cancel Options

Yes_cancel_option yes,cancel Options
