What is Constructor Overloading in Java?

Question

Accepted Answer

In Java, a constructor is just like a method but without return type. It can also be overloaded like Java methods.
Constructor overloading in Java is a technique of having more than one constructor with different parameter lists. They are arranged in a way that each constructor performs a different task. They are differentiated by the compiler by the number of parameters in the list and their types.
Example of Constructor Overloading

//Java program to overload constructors in java  
class Student5{  
    int id;  
    String name;  
    int age;  
    //creating two arg constructor  
    Student5(int i,String n){  
    id = i;  
    name = n;  
    }  
    //creating three arg constructor  
    Student5(int i,String n,int a){  
    id = i;  
    name = n;  
    age=a;  
    }  
    void display(){System.out.println(id+" "+name+" "+age);}  
   
    public static void main(String args[]){  
    Student5 s1 = new Student5(111,"Karan");  
    Student5 s2 = new Student5(222,"Aryan",25);  
    s1.display();  
    s2.display();  
   }  
}  

Output
111 Karan 0
222 Aryan 25
