Aggregating class

3. Create an aggregating class

Write a class called "Line". It should store two Point objects. It should have two
constructors, one that receives 4 ints to set the (x,y) of each end, and the other
that receives two Point objects.

It should have a distance method that computes the length of the line. Its toString
method should print like this: (x,y) to (x,y)

Write a main method that creates a line with each constructor. It should then print
each line and its length.





Output:



I am having the issue with the Point constructor and I am not sure where to go from here.

Any help is appreciated.

Why Point must be aggregated by Line instead of composition, because Point can "live" without Line?
 
I agree. Here's the link: http://aspose.com/file-tools
