ResultSet to Array

I have a Result set returned using a query: 

String query = "select Bookname, SubjectName from books join Subjects on Subjects.SubjectID = Books.subjectID where classID = '1a'";
ResultSet temp = null;
try
{
   Statement st = conn.createStatement();
   ResultSet rs = st.executeQuery(query);

   temp = rs;
}

I was just wondering is it possible to turn the Resultset into two seperate arrays: eg BookName[] and BookSubject[] so I can show them in a list view later on? Relatively new to resultset and this concept in android

You should be able to easily iterate through the results on the result set, populating each array with the results as you interate.

Something like this: 

...
ResultSet rs = st.executeQuery(query);

ArrayList<String> names = new ArrayList<String>();
ArrayList<String> subjects = new ArrayList<String>();

while (rs.next()) { 
    names.add(rs.getString(1));
    subjects.add(rs.getString(2));
}

// finally turn the array lists into arrays - if really needed
String[] nameArr = new String[names.size()];
nameArr = names.toArray(nameArr);

String[] subjectArr = new String[subjects.size()];
subjectArr = subjects.toArray(subjectArr);

Hope that helps!
