Answers for "how to overload a constructor"

constructor overloading

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.

class Student5{  
    int id;  
    String name;  
    int age;
    
    Student5(int i,String n){  
    	id = i;  					//creating two arg constructor
    	name = n;  
    }
    
    Student5(int i,String n,int a){  
    	id = i;  
    	name = n;					//creating three arg constructor    
    	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();  
   }  
}

Can we overload the constructors

Yes, the constructors can be overloaded by changing the number of 
arguments accepted by the constructor or by changing the data type of 
the parameters
