- x: int -y: int - Point + Point() + Point (xVal: int, yVal: int) + getX(): int + getY(): int + setpoint (newX: int, newY: int): void +toString(): String + distance (Point pnt): double 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 comma 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

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.

Hints: Use Math.pow(n, 2) to raise a number to a power. Use Math.sqrt(number) to find the square root of a number. Your output should look exactly the same as follows: The distance from (0, 0) to (3, 4) is: 5.0 P1 new coordinates are: X = 1 y = 4 P2 new coordinates are: X = 2 y = 3 The distance from (1, 4) to (2, 3) is: 1.4142135623730951
