java - create new object in arraylist with attributes -

i new java , starting work arraylists. trying create arraylist students. each student has different attribute associated them (name, id). trying figure out how add new student object attributes. here have:

arraylist < student > studentarray; public student(string name, int id) {   this.fname = name;   this.stid = id; } public stromg getname() {   return fname; } public int getid() {   return stid; } public boolean setname(string name) {   this.fname = name;   return true; } public boolean setidnum(int id) {   this.stid = id;   return true; } 

what need following:

import java.util.*;  class teststudent {     public static void main(string args[])     {         list<student> studentlist= new arraylist<student>();         student tempstudent = new student();         tempstudent.setname("rey");         tempstudent.setidnum(619);         studentlist.add(tempstudent);         system.out.println(studentlist.get(0).getname()+", "+studentlist.get(0).getid());     } }  class student {     private string fname;     private int stid;      public string getname()     {         return this.fname;     }      public int getid()     {         return this.stid;     }      public boolean setname(string name)     {         this.fname = name;         return true;     }      public boolean setidnum(int id)     {         this.stid = id;         return true;     } }
