Answer 1

Here you have my friend.

import javax.swing.*;

public class SampleProgram {

public static void main(String[] args) {
String firstName = JOptionPane.showInputDialog(null,"Enter first name");
String middleName = JOptionPane.showInputDialog(null,"Enter middle name");
String lastName = JOptionPane.showInputDialog(null,"Enter last name");

JOptionPane.showMessageDialog(null,"GoodDay "+firstName+" "+middleName+" "+lastName);
}
}

To get the input from user use showInputDialog method
To get the output use showMessageDialog method
And the ''null'' will get the dialog box to the center of the screen
