Hi friends,

I have doubt with instantmethods

{
private String name;
private int age;
   person(String name,int age)
     {
      this.name=name;
      this.age=age;
      }
     void display()
     {
     System.out.println("Name="+name);
     System.out.println("age ="+age);
     }
Object modify(Person obj)
{
obj.name="Laxmi";
}
 
 
}
class Demo
{
public static void main(String args[])
{
Person p1=new Person("Rajesh",20);
p1.display();
              //-------------------------
Person p2=p.modify(p1);
              //--------------------------

}
}

Hello Sri,

Always copy and paste your code from original location. You have made many mistakes while rewriting in this post.

The potential error that i could see is you haven't type cast from Object to person class.

person p2=(person) p1.modify(p1); 

Is this the actual problem?

Vishal Pandya is correct about copy and paste; your modify method returns an Object which needs to be cast to person.

And always use code tags round quoted code; I have added them so you can see how much easier the code is to read.
