Thread: JOPtionPane error

Hi guys im trying to make a JOption box that asks a user to input his/her name and display it back to them but keeping getting the following compile error: Cannot find symbol JOptionPane.showMessageDialog the code looks as follows, any input will be appreciated.

import javax.swing.JOptionPane;

public class Wack
{
public static void main(String args[])
{
String userInput = "";


userInput = JOptionPane.showInputDialog("Please enter your name");


userInput = "your name is " + userInput;

JOptionPane.showMesssageDialog(null, userInput);

}
}

you can pass any JComponent as Object in the conctructor for JOptionPane,

in your case is there null value - JOptionPane.showMessageDialog(null, "ErrorMsg", for example

JOptionPane.showMessageDialog(myFrame,
"ErrorMsg", "Failure", JOptionPane.ERROR_MESSAGE);

System.in.println( " " ) method is used to ask for a user input.

String [variable name] = " "; will do the trick. It will require an input from the user.
