📘 Step Learning

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

💻 Program Code

 class StudentCopy2{
    int rollno;
    String name;

    StudentCopy2(int i,String n){
    rollno = i;
    name = n;
    }

    StudentCopy2(){}

    void display(){
		System.out.println(rollno+" "+name);
		}

    public static void main(String args[]){
    StudentCopy2 obj1 = new StudentCopy2(1,"Rumman");
    StudentCopy2 obj2 = new StudentCopy2();

    obj2.rollno=obj1.rollno;
    obj2.name=obj1.name;

    obj1.display();
    obj2.display();
   }
}
