java - How to remove an object from an ArrayList? -

i want remove object arraylist based on students name , each object has 5 elements. question: how remove object text file.

arraylist<student> studentlist= new arraylist<student>(); iterator iter = studentlist.iterator();  public dvd remove(string removename) {     while (iter.hasnext()) {         (student stu : studentlist) {             if (stu .getname().touppercase().contains(removename.touppercase())) {                 system.out.println("found , removed");                 iter.remove();                 return stu ;             }              system.out.println("not found");         }     }     return null;  } 

each student read in text file. 1 element per line.

ex:

  john smith   undergrad   21 years old   2010   2014   pocahantas   professor   369 years old   1599   1603   etc... // new person   etc.... 

i don't think need iterator:

    public student remove(string removename) {         (student stu : studentlist) {             if (stu.getname().touppercase().contains(removename.touppercase())) {                 system.out.println("found , removed");                 studentlist.remove(stu);                 return stu;             }          }          system.out.println("not found");          return null;     }
