hi,

Perhaps, you are looking for the code like below :

import java.util.LinkedList;
import java.util.Iterator;
import java.util.List;
public class Patient {
    String name;
    String id;
    double weight;  

    public Patient(String name, String id, double weight) {
        super();
        this.name = name;
        this.id = id;
        this.weight = weight;       
    }

    public String getName() {
        return name;
    }

    public String getId() {
        return id;
    }

    public double getWeight() {
        return weight;
    }

    public Patient getPatient()
    {
        return  new Patient(name, id, weight);
    }

    public static void main(String args[])
    {
        Patient patient = new Patient("Ankit", "15", 45.85);
        Patient patient1 = new Patient("Bipul", "16", 50.85);
        Patient gPatient = patient.getPatient();
        Patient gPatient1 = patient1.getPatient();
        List list = new LinkedList();       
        list.add(gPatient.getId()+" "+gPatient.getName()+" "+gPatient.getWeight());
        list.add(gPatient1.getId()+" "+gPatient1.getName()+" "+gPatient1.getWeight());
        Iterator itr = list.listIterator();
        while(itr.hasNext())
        {
            System.out.println(itr.next());
        }       
    }
}
