Question

please help with program,these are he requirements: I am also getting a "missing return statement" in my milestone class

Create a new class Milestone which contains at least an event description, a planned completion date, and an actual completion date (which will be unset when the milestone is created). There should be a method to changed the planned completion date as well as a method to designate the Milestone as achieved. Add a method that returns whether the milestone has been missed, completed early, completed on time, completed late, or still due.

Create a unit test to exercise the Milestone class.

Add the ability for the project to have numbered milestones that can be retrieved in date order with notation concerning the milestone’s status as well as the description.

Update the unit test for the Project.

My Code:Milestone.java

public class Milestone {

private String eventdescription;
private Date expectedCompletionDate;
private Date actualCompletionDate;

  
public void milestoneTitle(String eventdescription){
this.eventdescription = eventdescription;
}
  
public void changeExpectedDate(Date date){
this.expectedCompletionDate = date;
}
/**
*
* @return MilestoneAchieved
*/
public String milestoneAchieved() {
if (this.actualCompletionDate != null) {
return "Milestone Achieved";
}   
}
/**
*
* @return
*/
public String milestoneStatus() {
Date d = new Date();
if (this.actualCompletionDate.before(this.expectedCompletionDate)) {
return "Milestone Completed Early";
}else if (this.actualCompletionDate.after(this.expectedCompletionDate)) {
return "Milestone Completed Late";
}else if (this.actualCompletionDate.equals(this.expectedCompletionDate)) {
return "Milestone Completed on Time";
}else if ((this.actualCompletionDate == null)&&(d.after(this.expectedCompletionDate))) {
return "Milestone Missed";
}else if ((this.actualCompletionDate == null)&&(d.before(this.expectedCompletionDate))) {
return "Milestone Still Due";
  
  
  
}

You have to made only one change ... save the event information in variable in if else statement the return it .......

/**************************Milestone.java*************************************/

import java.util.Date;

public class Milestone {

   private String eventdescription;
   private Date expectedCompletionDate;
   private Date actualCompletionDate;

   public void milestoneTitle(String eventdescription) {
       this.eventdescription = eventdescription;
   }

   public void changeExpectedDate(Date date) {
       this.expectedCompletionDate = date;
   }

   /**
   *s
   * @return MilestoneAchieved
   */
   public String milestoneAchieved() {
       if (this.actualCompletionDate != null) {
           eventdescription = "Milestone Achieved";
       }
       return eventdescription;
   }

   /**
   *
   * @return
   */
   public String milestoneStatus() {
       Date d = new Date();
       if (this.actualCompletionDate.before(this.expectedCompletionDate)) {
           eventdescription = "Milestone Completed Early";
       } else if (this.actualCompletionDate.after(this.expectedCompletionDate)) {
           eventdescription = "Milestone Completed Late";
       } else if (this.actualCompletionDate.equals(this.expectedCompletionDate)) {
           eventdescription = "Milestone Completed on Time";
       } else if ((this.actualCompletionDate == null) && (d.after(this.expectedCompletionDate))) {
           eventdescription = "Milestone Missed";
       } else if ((this.actualCompletionDate == null) && (d.before(this.expectedCompletionDate))) {
           eventdescription = "Milestone Still Due";

       }
       return eventdescription;
   }
}

Thanks a lot, Please let me know if you have any problem........
