java - Linked List steps -

i have project , don't know steps pierced

write java program store employee information in linked list, program should implement following functions:

• function
  task
• insert new employee
  add new employee linked list , store employee's information ( id, name, address, department, salary)
• update employee information
  modify existing employee's information (change address , salary only). should ask employee id update his/her information
• remove employee
  remove employee using employee id linked list

the program should display list of functions, , ask user enter number of function he/she wants do, perform function required in previous table.

this did

import java.util.scanner;  import java.util.linkedlist;  import java.util.collections;  import java.util.listiterator;    public class linkedlistemployee {            //------------start of employee class--------      private class employee {          private string empnumber;          private string name;          private string department;          private int emptest;          private double salary;          public employee() {              empnumber = null;              emptest= 0;              name = null;              department = null;              salary = 0.0;          }                }      //------------end of employee class--------                        public static void main(string args[]) {              linkedlist<employee> emptest = new linkedlist<employee>();              system.out.println("\nmenu\n1.add employee\n2.update");              scanner in = new scanner(system.in);              int choice = in.nextint();              if (choice == 2)                  system.out.println("enter employee’s name");              string nm = in.nextline();             update(nm, emptest);          }          public static void update(string namepara, linkedlist<employee> emptest) {              listiterator<employee> litr = emptest.listiterator();              employee tempemp;              scanner in = new scanner(system.in);              while (litr.hasnext()) {                  tempemp=litr.next();                  if (tempemp.name.equals(namepara)) {                      system.out.println("enter new address");                      string add = in.nextline();                      system.out.println("enter new salary");                      string sal = in.nextline();                      //tempemp.empaddress = add;                      tempemp.salary = double.parsedouble(sal);                      break;                  }              }          }  }

it work ?? or there more steps go !! referring question ?

please me know steps

based on comment in response error getting ("listiterator litr = emptest.listiterator(); cannot find symbol - class listlterator"):

the type listiterator unknown, looking listiterator, change

listiterator<integer> litr = emptest.listiterator();  

to

listiterator<integer> litr = emptest.listiterator();  

---

edit next error after then: "listiterator litr = emptest.listiterator(); cannot find symbol - variable emptest":

that list visible within scope of main method since it's declared in there. 1 possibility pass list along method call, change

public static void update(string name) { 

to

public static void update(string name, linkedlist<employee> emptest) { 

and pass missing list update method main method:

update(nm, emptest); //instead of update(nm); 

alternatively, can widen scope of list , declare entire class, mentioned in comments @dude, should handled care, heightens retained state of object (or class in case) in question.

aside: types capitalized in java (employee should employee), whereas variables , methods start lower case (update() should update()). take @ this article, please.
