Q:
Triangle class
a) Use lengths of sides as attributes. Alternatively use co-ordinates of corners. data types to be used ( String, double, int)
b) Code a constructor that takes three lengths as inputs
c) Code a second constructor that takes one length as input (equilateral).
d) Code a third constructor that has no inputs and sets the lengths as 3,4,5
e) Code methods to get perimeter and get length of sides
f) Code a method to set length of sides

The Triangle class should have a TriangleTest driver class to run it. In this class build at least 3 Triangle objects, one per constructor and run all methods at least once to test that the methods work at least once.

A:
Preview: ... 2 = s2; side3 = s3; } </pre> Then we can compute the perimeter, which is just the sum of the sides, by this simple method: <pre> // return the perimeter of the triangle (sum of side lengths) public double perimeter() { return side1 + side2 + side3; } </pre> The methods to get and set the the side lengths are simple and almost identical to each other. Here's what we'd write for the first side ...
