Learn this program step-by-step with algorithm, source code, output and detailed explanation.

💻 Program Code

 class ParameterizedConstructor{
    int rollno;
    String name;

   // it is constructor
     ParameterizedConstructor(int i,String n){
	    rollno = i;
	    name = n;
	    }
	    
   // it is method
    void display(){
		System.out.println(rollno+" "+name);
		}

    public static void main(String args[]){
    ParameterizedConstructor s1 = new ParameterizedConstructor(1,"Rahim");
    ParameterizedConstructor s2 = new ParameterizedConstructor(2,"Ram");
    s1.display();  // invoke method using object s1
    s2.display();  // invoke method using object s2

   }
}
