OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Given the UML diagram above, complete the Point class that models a point on a
Cartesian plane, the class should have the following instance variables,
constructor(s) and instance methods:
Two private integer instance variables, x and y.
A "no-arg" constructor that creates a point with the coordinates (0, 0).
An overloaded constructor that takes two integer parameters xVal and
yVal and set the instance variables accordingly.
A getter method for each instance variable.
A method named setPoint that takes two integer parameters newx and
newY and set the instance variables accordingly.
A method named toString which takes no parameters, and returns a
string with the coordinates of the point within parentheses and commal
separated, for example: (2, 5)
A method named distance which takes one class parameter of type
Point, the method returns the distance (a double value) from the (x, y)-
location of the Point object that calls the method to the (x, y)-location of
the Point object passed in.
The distance between two point is calculated by the formula:
√(x₁ - x₂)² + (y₁ - y₂)²

Use Math.pow(n, 2) to raise a number to a power.
Use Math.sqrt(number) to find the square root of a number.
