Design and implement an application name the driver class Pa

Design and implement an application (name the driver class Part3) that reads a sequence of up to 25 pairs of names and postal codes for individuals from a file named activity 1. inp (E.g. each line of the data file should contain a person\'s name and a standard 5 digit zip code). Read in the data from the input file and 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 white space. Your data should be stored in a Person class that you design that contains a default (no argument) constructor, accessors and mutators for all data, and a toString method used in the printing. After the input has been read in, use a for loop to iterate through the 25 objects and print the string representation of each data object by calling your toString method for the class that stores the data. You are required to create your own input file and to include it in the jar file you will use to deliver your lab. Your program should work though with any input file following the described format. Use an array of Person objects to store the data objects.

Solution

/**
*
* The java class Person that represetnts
* the object of person*/
//Person.java
public class Person {

   private String firstName;
   private String lastName;
   private int zipcode;
  
   public Person() {
       firstName=\"\";
       lastName=\"\";
       zipcode=0;
   }
  
   //Mutator/setter methods
   public void setFirstName(String firstName){
       this.firstName=firstName;
   }
   public void setLastName(String lastName){
       this.lastName=lastName;
   }
   public void setZipCode(int zipcode){
       this.zipcode=zipcode;
   }
  
   //Accessor/getter methods
   public String getFirstName(){
       return firstName;
   }
   public String getLastName(){
       return lastName;
   }
   public int getZipCode(){
       return zipcode;
   }
  
   //Returns string description of the Person object
   @Override
   public String toString() {      
       return String.format(\"%-15s%-15s%-10d\", firstName,lastName,zipcode);
   }
      
}
