Instructions 1. Eclipse, create a package called finalanswer. Copy and place into the package the file TestFinalAnswer.java provided below n the package, create a class called FinalAnswer. All of the static methods you are asked to write will go in this class

Explanation / Answer

FinalAnswer.java:

package finalanswer;

public class FinalAnswer {
  
   /*
   * I am providing the method below as per the given guidlines
   * You should put your name below in place of 'Henry' and 'Smith'
   * inside the double quotes
   */
   public static String yourName() {
       // please put your own first name
       String firstName = "Henry";
      
       // please put your own last name
       String lastName = "Smith";
      
       return lastName + ", " + firstName;
   }
}

Please replace the first and last name above as pointed in comments. I don't know your name else i would have done it for you.
