Question

Design and implement an application that reads a sequence of up to 25 pairs of names and postal (ZIP) codes for individuals. 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.

Answer 1

Answer:

Kindly go to the explanation for the answer.

Explanation:

Person.java

public class Person{

private String firstName, lastName;

private int zip;

public Person(String firstName, String lastName, int zip) {

super();

this.firstName = firstName;

this.lastName = lastName;

this.zip = zip;

}

public String toString() {

String line = "\tFirst Name = " + this.firstName + "\n\tLast Name = " + this.lastName;

line += "\n\tZip Code = " + this.zip + "\n";

return line;

}

}

Test.java

import java.util.ArrayList;

import java.util.Scanner;

public class Test{

public static void main(String args[]) {

Scanner in = new Scanner(System.in);

ArrayList<Person> al = new ArrayList<Person>();

for(int i = 0; i < 25; i++) {

System.out.print("Enter person details: ");

String line = in.nextLine();

String words[] = line.split("\t");

String fname = words[0];

String lname = words[1];

int numb = Integer.parseInt(words[2]);

Person p = new Person(fname, lname, numb);

al.add(p);

}

for(int i = 0; i < 25; i++) {

System.out.println("Person " + (i + 1) + ":");

System.out.println(al.get(i));

}

}

}
