         List records = new ArrayList(10);

         // Iterating student list and put it into new String array List
         for (Student stud : studentList) {
            List record = Arrays.asList(stud.getId(), stud.getName());

            String recordArray[] = new String[record.size()];
            record.toArray(recordArray);
            records.add(recordArray);
         }

         // Writing string arrayList in to Stringwriter

         csvWriter.writeAll(records);

         // Spring String writer as csv records
         System.out.println("CSV Details");
         System.out.println(writer.toString());

      } catch (Exception e) {
         e.printStackTrace();
      }

   }
}

class Student {
   private String id;
   private String name;

   public Student(String id, String name) {
      super();
      this.id = id;
      this.name = name;
   }

   public String getId() {
      return id;
   }

   public void setId(String id) {
      this.id = id;
   }

   public String getName() {
      return name;
   }

   public void setName(String name) {
      this.name = name;
   }

}
