Question
Look at the API of the Point class and find out how to construct a Point object. Write a Java program
“PointTester”, that constructs two points with coordinates (3, 4) and (–3, –4). Find the distance
between them, using the distance method. Print the distance, as well as the expected value. (You may
draw a sketch on graph paper to find the value you will expect.)
- Update your program so it randomly select coordinate points (x,y), where −50 ≤ ? ≤ 50 ??? ? ∈
[−90, 90].
