Making a program to print "Hello [name]!"

I'm very very new to Java, currently taking a college course in it. I'm supposed to start with the following program, and change it so that when the user types in their name, the program will print "Hello, [name]!" I have absolutely no idea where to start, and would enormously appreciate any help you folks could give.
import javax.swing.J0ptionPane;

public class DialogViewer
public static void main(String[] args)
String name = J0ptionPane.showInputDialog("What is your name?");


  • Not sure why you double posted, but you can do this with the code below.

    import javax.swing.*;

    public class Test {

    public static void main(String[] args) {
    String name = JOptionPane.showInputDialog("What is your name?");
    System.out.println("Hello, " + name);
