Question

City 1	1	1
City 2	1	3
City 3	4	1
City 4	5	3
City 5	3	5

in java Create 5 city objects and initialize their location (x and y) using the above table. Then put all of the five cities in a vector.

Answer 1

code:

import java.util.*;
class City {//creating a class
   String name;
   int x,y;
   City(String name,int x,int y)//constructor to intitialise variables
   {
       this.name=name;
       this.x=x;
       this.y=y;
   }
}
class Vector_Example {
   public static void main(String[] args)
   {
       Vector v = new Vector();//creating a vector
       Scanner sc=new Scanner(System.in);//scannwe class to read input
       for(int i=0;i<5;i++)
       {
           System.out.println("Enter name, x,y:");
           String name=sc.next();
           int x=sc.nextInt();
           int y=sc.nextInt();
           City c=new City(name,x,y);//creating a city object
           v.add(c);//adding it to vector
       }
       System.out.println("The Objects in Vector are");
       for(int i=0;i<5;i++)
       {
           City c =(City)v.get(i);//obtaining the object
           System.out.println(c.name+" "+c.x+" "+c.y);
       }
   }
}

output:
