Question

I am facing some difficulties while assigning the values in an array list. My code is :

while (answer.hasMore()) {
  SearchResult rslt = (SearchResult)answer.next();
  Attributes attrs = rslt.getAttributes();
  System.out.println();
  if (attrs.get("department") != null && attrs.get("telephonenumber") != null) {
      System.out.println(attrs.get("department") + " " + attrs.get("name") + " " +
                         attrs.get("Description") + " " + attrs.get("mail") + " " +
                         attrs.get("telephonenumber")+
                         attrs.get("samaccountname") + attrs.get("samaccountname") );
}

I want to assign the values of attrs.get("department") + attrs.get("description")+ attrs.get("name")+attrs.get("mail") each one to an array list.

I tried to define at the beginning:

String[] name = new String[100];

and in the while loop i tried to read the name attribute, I tried to do:

name = attrs.get("name");

But it did not work. Can anyone help.

You cannot directly assign strings to a array made of string “references”. You need to index it first. But it would be much better to actually use a list (and maybe convert it to an array later). Check out List and ArrayList in the Java documentation.

As an example:

    Attributes attrs = new Attributes();
    List<String> attribValues = new ArrayList<String>();
    System.out.println();
    if (attrs.get("department") != null
            && attrs.get("telephonenumber") != null) {
        System.out
                .println(attrs.get("department") + " " + attrs.get("name")
                        + " " + attrs.get("Description") + " "
                        + attrs.get("mail") + " "
                        + attrs.get("telephonenumber")
                        + attrs.get("samaccountname")
                        + attrs.get("samaccountname"));
        attribValues.add(attrs.get("department"));
        attribValues.add(attrs.get("telephonenumber"));
    }

    final String[] attribArray = attribValues.toArray(new  String[attribValues.size()]);
