List<TrainingModel> traininglist = viewTraining(biodataId);

and there's my trainingmodel class

public class TrainingModel {
    @Id
    @Column(name="id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;
    @Column(name="is_delete")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private boolean isDelete;
    @Column(name="biodata_id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long biodataId;
    @Column(name="training_name")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private String trainingName;
    @Column(name="organizer")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private String organizer;
    @Column(name="training_year")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private String trainingYear;
    @Column(name="training_month")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private String trainingMonth;
    @Column(name="training_duration")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int trainingDuration;
        //getter setter

}

Answer 1

To see all the objects in the arrayList, you can use: System.out.println(traininglist);

or you can loop through the training list like this:

for(TrainingModel listElement : traininglist){
    listElement.(use the getter of any of the fields to get the Object property)
}

Hope this helps.
