How to get a list of specific fields values from objects stored in a list?

Question

Say I have an list of objects with two fields field1 and field2, both of String type.

How do I get a list of all field1 values wit

Answer 1

Add the values of records in different lists and by using the one or two iterator simply print the seperate values.like follows:

rs=st.executeQuery("select * from stu");
List data=new ArrayList();
List data1=new ArrayList();
while(rs.next())
{
   data.add(rs.getString(1));
   data1.add(rs.getString(2));
}
Iterator it=data.iterator();
Iterator it1=data1.iterator();
while(it1.hasNext())
{
   System.out.println(" "+it.next()+"  "+it1.next());
}
