Using JOptionPane to get input

Using JOptionPane to get input

Another way to get input from the user is using the class JoptionPane obtained from the javax.swing package. JoptionPane make it easy to create a standard dialog box that provides a value to the user or inform something.
Give the following code,
import javax.swing.JOptionPane;
public class GetInputFromKeyboard

public static void main (String [] args) (
String name = "";
name = JoptionPane.showInputDialog ( "Please enter your name");
String msg = "Hello" + name + "!";
JOptionPane.showMessageDialog (null, msg);
)
)
produce output:


















Statement first,
import javax.swing.JOptionPane;
Explain that we import the class from the javax.swing package JoptionPane.
Can also write,
import javax.swing .*;
next statement,
name = JOptionPane.showInputDialog ( "Please enter your name");
creating a JOptionPane input dialog, which displays a dialog with a message, a
textfield and the OK button as shown. Results from the dialogue and String is stored
in the variable name.
Now we create a welcome message, which will be stored in the variabe msg,
String msg = "Hello" + name + "!";
Next line is a dialog that displays a message and have the OK button,
JOptionPane.showMessageDialog (null, msg);
