I don't understand why he writes that line?
Why does he have to create an instance of Numwords?
One can delete this line and still the program runs smoothly. Can you
give me the link where he explains this or if it doesn't exist, try to
explain this for me?
Thanks in advance

import javax.swing.JOptionPane;
public class NumWords {
/** Creates a new instance of NumWords */
public NumWords() {
}
/**

*/
public static void main(String[] args) {
String msg = "";
int input = 0;
// Get the input string
input = Integer.parseInt(JOptionPane.showInputDialog
("Enter number between 1 to 10"));
// Set msg variable to the string equivalent of input
if(input == 1) msg = "one";
else if(input == 2) msg = "two";
else if(input == 3) msg = "three";
else if(input == 4) msg = "four";

else if(input == 7) msg = "seven";
else if(input == 8) msg = "eight";

else if(input == 10) msg = "ten";
else msg = "Invalid number";
// Display the number in words if with in range
JOptionPane.showMessageDialog(null,msg);
}
