THIS IS A GROUP ASSIGNMENT/PROJECT

Using Eclipse, create a Java Project named TimeSpan.

Define a class named TimeSpan. A TimeSpan object stores a span of time in hours and minutes (for example, the time span between 8:00am and 10:30am is 2 hours, 30 minutes). Each TimeSpan object should have the following public methods:

• TimeSpan(hours, minutes)
  
  • Constructs a TimeSpan object storing the given time span of minutes and seconds.
    

• Write two contructors:
• without parameters
• with parameters

• getHours
  
  • Returns the number of hours in a TimeSpan.
  
  
• getMinutes
  
  • Returns the number of minutes in a TimeSpan, between 0 and 59.
  
  
• isGreater
  
• Compares two TimeSpans and returns a boolean indicating if the first is greater than the second.
  

• add(hours, minutes)
  
  • Adds a given amount of time to a TimeSpan. For example, (2 hours, 15 min) + (1 hour, 45 min) = (4 hours). Assume that the parameters are valid: the hours are non-negative, and the minutes are between 0 and 59.
  
  
• add(timespan)
  
  • Adds the amount of time stored in a TimeSpan to a TimeSpan and returns a new TimeSpan containing the result.
  
  
• getTotalHours
  
  • Returns the total time in a TimeSpan as the real number of hours, such as 9.75 for (9 hours, 45 min).
  
  
• getTotalMinutes
  
• Returns the total time in a TimeSpan as the total number of minutes.

• addTimeSpans
  • Takes three TimeSpans and adds the first two, storing the result in a third.

• printTimeSpan
  
  • Returns a string representation of the TimeSpan of hours and minutes, such as "28h46m".

• main
  
  • Create at least three TimeSpan objects demonstrating both constructors above.
  • Test ALL methods created above.
  • Use single-line comments to label method types. (constructor, pure, modifier, fill-in )
    

The minutes should always be reported as being in the range of 0 to 59. That means that you may have to "carry" 60 minutes into a full hour.

Whenever possible, you should use existing methods when writing methods.

When complete, group leaders should use PasteBin to share the code with their group members. Share with Mr. Merriman as well.
