Java program to find distance between two points in a plane

import java.io.*; class distance {             int x,y,dist;             distance()              {  x=0;               y=0;  }   void calc(distance c,distance d)   {      int xd=c.x-d.x;      int xs=xd*xd;      int yd=c.y-d.y;      int ys=yd*yd;      int sum=xs+ys;      double dist=Math.sqrt(sum);      System.out.println("The distance is "+dist);   }   void read()throws IOException   {      BufferedReader br=new BufferedReader(new InputStreamReader(System.in));      System.out.println("Enter the x coordinate");      x=Integer.parseInt(br.readLine());      System.out.println("Enter the y coordinate");      y=Integer.parseInt(br.readLine());      System.out.println("The entered point is "+"("+x+","+y+")");   }   public static void main(String s[])throws IOException   {      distance c=new distance();      distance d=new distance();      System.out.println("First point");      c.read();      System.out.println("Second point");      d.read();      d.calc(c,d);   } } Output
