## TimeTracker
### Instructions
Write a `ProjectTime` class to track the duration of a project using start and end times. You will be asked to add getter and setter methods for the `startTime` and `endTime` attributes. When you set one of them, you must update the `hoursLogged` attribute. The `hoursLogged` getter should output the hours in the following format:
- Less than 120 minutes: `hoursLogged` m
- Less than 120 hours: `hoursLogged` h
- Less than 120 days: `hoursLogged` d
- More than 120 days: `hoursLogged` mo
If there is any error, the number of `hoursLogged` should be handled accordingly.
> 💡 The `hoursLogged` shouldn't be a negative number except -1 in case of errors.
### Expected Functions
```java
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class ProjectTime {
private String startTime;
private String endTime;
private float hoursLogged;
public ProjectTime(String start, String end);
public void setStartTime();
public void setEndTime();
public String getStartTime();
public String getEndTime();
public String getHoursLogged();
}
```
### Usage
Here is a possible `ExerciseRunner.java` to test your function :
```java
public class ExerciseRunner {
public static void main(String[] args) {
ProjectTime shortProject = new ProjectTime("2023-05-14 09:00", "2023-05-14 09:30");
System.out.println("Short Project Total Logged Time: " + shortProject.getHoursLogged());
ProjectTime overnightProject = new ProjectTime("2023-05-14 20:00", "2023-05-15 08:00");
System.out.println("Overnight Project Total Logged Time: " + overnightProject.getHoursLogged());
ProjectTime fullDayProject = new ProjectTime("2023-05-14 00:00", "2023-05-15 00:00");
System.out.println("Full Day Project Total Logged Time: " + fullDayProject.getHoursLogged());
ProjectTime errorProject = new ProjectTime("2023-05-14", "2023-05-15 08:00");
System.out.println("Error Project Total Logged Time: " + errorProject.getHoursLogged());
}
}
```
and its output :
```shell
$ javac *.java -d build
$ java -cp build ExerciseRunner
Short Project Total Logged Time: 30 m
Overnight Project Total Logged Time: 12 h
Full Day Project Total Logged Time: 24 h
Error Project Total Logged Time: -1
$
```
