Input from text file into linked list and displays in output file, also searched through index for date - linked-list

Question

Trying to get a linked list to read input from a file, put it into a linked list, search for same date, and write back into a file, UserLoginTest cannot be changed
public class User {``
String name;
int id;
String login;
double duration;
public User() {
name="";
id=0;
login="";
duration=0.0;
}
public User(String n,int i, String l, double d) {
n=name;
i=id;
l=login;
d=duration;
}
public void setName(String n) {
name=n;
}
public void setId(int i) {
id=i;
}
public void setLogin(String l) {
login=l;
}
public void setDuration(double d) {
duration =d;
}
public String getName() {
return name;
}
public int getId() {
return id;
}
public String getLogin() {
return login;
}
public double getDuration() {
return duration;
}
}
public class Node{
public User data;

public Node(User u) {
data=u;
}
public Node(User u, Node n) {
data = u;
next = n;
}
public String toString() {
return data+"";
}
