Overloaded Constructors

This program demonstrates constructor overloading.

Problem Statement

Write a Java program with overloaded constructors in Student class.

Source Code

1	class Student {
2	String name; int age;
3	Student(){ name="Unknown"; age=0; }
4	Student(String n,int a){ name=n; age=a; }
5	}
6	public class ConstructorOverloading {
7	public static void main(String[] args) {
8	System.out.println("Eduinq Constructor Overloading");
9	Student s1=new Student();
10	Student s2=new Student("Arun",20);
11	System.out.println("Student1: "+s1.name+", Age: "+s1.age);
12	System.out.println("Student2: "+s2.name+", Age: "+s2.age);
13	}
14	}

Program Output

Eduinq Constructor Overloading
Student1: Unknown, Age: 0
Student2: Arun, Age: 20

Explanation

Multiple constructors defined. - Objects initialized differently. - Together demonstrates constructor overloading. Conclusion: Shows how to overload constructors.
