Task: Given input file A, translate the content to produce output file B
Hi there,

I need help in solving this domain problem. Any help will be appreciated.

====Scenario==========
File A: Consists of multiple lines of data whereby each line is of form
X;1.9,2;3,4.3; 5,6

Output file B, should consists of one line per shape and should be formatted as follows.
Shape[TRIANGLE], Points[[[3.0,3.0], [5.0, 8.0], [8.0,4.0]]], Area[9.0]

This should be supporting 4 shape types: Circle, Square, Triangle, Rectangle.

This should demonstrate OO principle and use Factory design patten and Unit tests.

Note: Input File A has these cartisean coordinates which have to be read and determine the shape type;

t: 3,3; 5,8; 7,4
s:-1,-6; -1,-3; 2, -3; -2, -6
c: -4, -3; -2,-1
r:-1,1;4,1; -5; -1,-5

What do you not understand? The first letter is obviously the shape, and the points are on a grid. So figure out the lengths of the sides/radius and do the multiplication work. We are not going to do your homework for you.

Hello,
Thanks for your reply. I am trying to improve myself in java as a whole. This is not a work which need to be submitted for any personal gain. I, therefore can calculate the area of all the shapes, but when it comes to determine the shape type I am stuck. Also, it will benifit me to see how other people attemp this problem. Any help is much appreciated.

Like I said, the first letter, obviously, identifies the shape.
