Question

Written in JAVA Coding

Write a java project that reads a sequence of up to 25 pairs of names and postal (ZIP) codes for individuals (sample input data is attached). Store the data in an object designed to store a first name (string), last name (string), and postal code (integer). Assume each line of input will contain two strings followed by an integer value, each separated by a tab character. Then, after the input has been read in, print the list in an appropriate format to the screen.

CODE IN JAVA:

Address.java file:

import java.util.ArrayList;
import java.util.Scanner;
public class Address {
   String fname;
   String lname;
   int zipcode;
   Address(String fname,String lname,int zipcode){
       this.fname = fname;
       this.lname = lname;
       this.zipcode = zipcode;
   }
   public String toString() {
       return this.fname+" "+this.lname+" "+this.zipcode;
   }
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       int n;
       System.out.print("Enter an integer(upto 25):");
       n = sc.nextInt();
       String fname,lname;
       int zipcode;
       ArrayList<Address> addr = new ArrayList<Address>();
       sc.nextLine();
       for(int i=1;i<=n;i++) {
           System.out.print("Enter first name:");
           fname = sc.nextLine();
           System.out.print("Enter last name:");
           lname = sc.nextLine();
           System.out.print("Enter zip code:");
           zipcode = sc.nextInt();
           sc.nextLine();
           Address ad = new Address(fname,lname,zipcode);
           addr.add(ad);
       }
       System.out.println("\nFname Lname Zipcode");
       System.out.println();
       for(Address a:addr) {
           System.out.println(a);
       }
   }

}
OUTPUT:
