Person Management System in Java

This repository contains a Java project that manages information about people. The program includes classes for defining person attributes, handling user input, and performing operations such as displaying and manipulating person data.

Features

• Person Attributes: Defines attributes such as name, age, and address for a person.
• User Interaction: Handles user input to create and manage person data.
• Data Display: Outputs the details of the people managed by the system.

Code Snippets

Main Class

The main class initializes the program, handles user input, and invokes methods for managing person data.

public class Principal {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        List<TPersona> people = new ArrayList<>();

        System.out.print("Enter the number of people: ");
        int numberOfPeople = scanner.nextInt();
        scanner.nextLine();  // Consume newline

        for (int i = 0; i < numberOfPeople; i++) {
            System.out.print("Enter name: ");
            String name = scanner.nextLine();

            System.out.print("Enter age: ");
            int age = scanner.nextInt();
            scanner.nextLine();  // Consume newline

            System.out.print("Enter address: ");
            String address = scanner.nextLine();

            TPersona person = new TPersona(name, age, address);
            people.add(person);
        }

        System.out.println("List of people:");
        for (TPersona person : people) {
            System.out.println(person);
        }
    }
}

Person Class

The TPersona class represents a person with attributes such as name, age, and address. It includes methods for displaying person details.

public class TPersona {
    private String name;
    private int age;
    private String address;

    public TPersona(String name, int age, String address) {
        this.name = name;
        this.age = age;
        this.address = address;
    }

    @Override
    public String toString() {
        return "Name: " + name + ", Age: " + age + ", Address: " + address;
    }
}

Usage

1. Compile the Java files using a Java compiler (e.g., javac).
2. Run the main class (Principal) to start the program.
3. Follow the prompts to enter the details of each person.
4. The program will display the list of people with their details.

Classes and Methods

• Principal: The main class that handles user input and program execution.
  • main(String[] args): The entry point of the program.
• TPersona: A class representing a person with attributes and methods for displaying details.
  • TPersona(String name, int age, String address): Constructor that initializes the person's attributes.
  • toString(): Method that returns the string representation of the person's details.
