the question is Look at the API of the Point class and find out how many to construct a Point object. In a PointTester program, construct two points with coordinates (-3,-4). Find the distance between them, using distance method. Print the distance, as well as the expected value.


I've been trying for a bit now and still have nothing.

is this java or is this javascript? big difference.

and what is "expected value"? you mean the statistical term?

step 1. what is the constructor of the Point class?
step 2. how do you call the constructor above?
step 3. how do you find the distance between two points geometrically (non-coding)?
step 4. how do you use step 3 via code?

I would guess there's a java API for the distance between 2 points already. Don't need to duplicate work.

He means java

I doubt that's what "expected value" means in this prompt, but who knows lol

i found this web site but im sick atm and need to go to bed (hence one of the reason's I cannot figure this out on my own) there will be a payment if you can figure it out while i take some meds and pass out (need by tomorrow 11 central time)

1.
The Point class has several constructors.

Point() gives a point at (0, 0)
Point(x, y) gives a point at (x, y)
Point (Point x) gives a point at the position of Point x.

2.

pointA = new Point(-3, -4);
pointB = new Point(-3, -4); // or pointB = new Point(PointA);

3.

System.out.println(pointA.distance(pointB));
System.out.println("Expected: 0 due to same location.");

For the full API, check the oracle docs you can find via google.
