I have a computer science test on Monday which will have a very
similar question to the one below. If you could please have an answer
before Sunday, I would greatly appreciate it!! I am completely new to
java and want to see the code for this so that I can study and
understand it. The question is:

Create a Triangle class that implements all of the missing code from
the template below (fill in the missing code):

public class Triangle
{
private Coordinate a, b, c;

//default constructor: should generate random Coordinates
public Triangle();

//standard constructor
public Triangle(Coordinate newA, Coordinate newB, Coordinate newC);

//accessors
public Coordinate getVertexA();
public Coordinate getVertexB();
public Coordinate getVertexC();

public double getSideA();
public double getSideB();
public double getSideC();

public double getAngleA();
public double getAngleB();
public double getAngleC();

public boolean isValid();
public boolean isScalene();
public boolean isIsosceles();
public boolean isEquilateral();

public double getPerimeter();
public double getArea();

public String toString();
public boolean equals(Object o);

public boolean contains(Coordinate t);
public Circle getCircumcircle();
public Circle getIncircle();
}

That's all for the question.

Some auxiliary classes you may want to use to help you out:

public class Coordinate
{
//state variable(s)
private double x;
private double y;

//constructor function(s)
public Coordinate();
public Coordinate(double newX, double newY);
public Coordinate (Coordinate toBeCopied);

//accessor function(s)
public double getX();
public double getY();

//utility function(s)
public double distanceTo(Coordinate target)
{
double deltaX = x - target.getX();
double deltaY = y - target.getY();
double hypotSquared = (deltaX * deltaX) + (deltaY * deltaY);
return (Math.sqrt(hypotSquared));
}

public String toString()
{return ("(" + x + "," + y + ")")}
}

public class Circle
{
private Coordinate origin;
private double radius;

public Circle();
public Circle(Coordinate newOrigin, double newRadius);
}

This is NOT an actual exam question, just one posed in a book for
solving that I tried to do and couldn't figure out. This answer is not
for credit in a course.

Hi alex1977-ga,

You may want to reconsider your list price for the type of work you
are requesting. Remember that researchers receive 75% of the list
price.

Personally, I would be willing to answer this question for a $100 list price.

Thanks,

In order to expedite the process, forget the code for the last three segments:

public boolean contains(Coordinate t);
public Circle getCircumcircle();
public Circle getIncircle();

Please answer soon! Time is incredibly important in this case!
