Answer:

import java.util.Scanner;

import java.lang.Math;

public class CoordinateGeometry{

    public static void main(String []args){

       double x1 = 1.0;

       double y1 = 2.0;

       double x2 = 1.0;

       double y2 = 5.0;

       double pointsDistance = 0.0;

       

       //Declare a variable to hold the result of (x2 - x1)²

       double x;

       

       //Solve (x2 - x1)^2 and store result in the variable x

       x = Math.pow(x2 - x1, 2);

       

       //Declare a variable to hold the result of (y2 - y1)²

       double y;

       

       //Solve (y2 - y1)^2 and store result in the variable y

       y = Math.pow(y2 - y1, 2);

       

       //Now pointsDistance = SquareRootOf(x + y)

       pointsDistance = Math.sqrt(x + y);

       

       System.out.println("Points distance: ");

       System.out.println(pointsDistance);

       

       return;

    }

}

Sample Output:

Points distance:  

3.0
