Explanation / Answer

Answer

import java.util.Scanner;

public class HelloWorld

{

public static void main (String[] args)

{

System.out.println("Enter four real Numbers for x1,y1,x2,y2 : ");

double x1,x2,y1,y2;

Scanner sc=new Scanner(System.in);

x1=Double.parseDouble(sc.next());

y1=Double.parseDouble(sc.next());

x2=Double.parseDouble(sc.next());

y2=Double.parseDouble(sc.next());

double dist=Math.sqrt(Math.pow(x2-x1,2)+Math.pow(y2-y1,2));

double m1,m2;

m1=(x1+x2)/2.0;

m2=(y1+y2)/2.0;

System.out.println("Points: ("+(Math.round(x1*10.0)/10.0)+","+(Math.round(y1*10.0)/10.0)+")("+(Math.round(x2*10.0)/10.0)+","+(Math.round(y2*10.0)/10.0)+")");

System.out.println("Distance : "+(Math.round(dist*10.0)/10.0));

System.out.println("Midpoint : "+(Math.round(dist*10.0)/10.0));

}

}
