how would I display this

[drgnfire25]

I created this and cant figure out how to display the return value, if anyone knows please help me out.

   public List< graduate > getAllPeople()
   {
      List< graduate > results = null;
      ResultSet resultSet = null;

      try
      {
         // executeQuery returns ResultSet containing matching entries
         resultSet = selectAllPeople.executeQuery();
         results = new ArrayList< graduate >();

         while ( resultSet.next() )
         {
            results.add( new graduate(resultSet.getInt("studentID"),
                                           resultSet.getString("firstName"),
                                           resultSet.getString("lastName"),
                                           resultSet.getFloat("gpa"),
                                           resultSet.getString("Status"),
                                           resultSet.getString("mentor"),
                                           resultSet.getString("thesisTitle"),
                                           resultSet.getString("thesisAdvisor")));

         } // end while
      } // end try
      catch ( SQLException sqlException )
      {
         sqlException.printStackTrace();
      } // end catch
      finally
      {
         try
         {
            resultSet.close();
         } // end try
         catch ( SQLException sqlException )
         {
            sqlException.printStackTrace();
            close();
         } // end catch
      } // end finally

      return results;
   }

You cannot display a List. What you need to do is iterate over the List and display each item.

so how would I do that from another class? I tried this but it says I cannot be referenced from a static context??

        List results = studentQueries.getAllPeople();
              Iterator<results> itr = results.iterator();
                while (itr.hasNext()) {
                  results element = itr.next();
                  stuData.append(element + "\n ");

In what class is the getAllPeople method?

Is studentQueries a variable of that class?

[Junky]

By the way, it helps if you copy and paste the EXACT error message. Usually it contains vital information that gets omitted when people paraphrase.

[drgnfire25]

studentQueries is the class that contains the method getAllPeople... the above code is in StudentView class

[drgnfire25]

exact error "non-static method getAllPeople() cannot be referenced from a static context"

[Junky]

Wow, your compiler must hate you. Whenever I get error messages they look more like this

est.java:4: cannot find symbol
symbol  : method doStuff()
location: class Xfoo
        f.doStuff();
         ^
1 error

My compiler provides lots more information than yours.

Since getAllPeople method is not static that means you cannot call it on the class. You must call it on an instance of the class. eg do you do this and expect the output to be 'h'?

String s = "hello";
System.out.println(String.charAt(0));

What junky is humorously telling you is that this is not the complete error message, and that if you supply more complete information, you'll likely get better help.

got it... called an instance and got it... tks
