Constructor Overloading: Person Class

In this problem: You will implement a Person class with three overloaded constructors that accept different arguments, create instances using each constructor, and display person information.

Learning Objective: Understand constructor overloading and learn initialization patterns with different arguments

Overview

Define three constructors in the Person class:

• Person(): Sets name to "Unknown" and age to 0
• Person(String name): Sets the given name, age defaults to 0
• Person(String name, int age): Sets both name and age

Specifications

• Define name (String) and age (int) fields in Person class
• display() method outputs "Name: [name], Age: [age]"
• In Main class, create instances using each constructor and call display()

Output Format

Name: Unknown, Age: 0
Name: Alice, Age: 0
Name: Bob, Age: 25
