how do I set an entity to read in a list<string> from another entity?

User_DTTUY

I have 2 entities - tutor and Subject.

At the controller, I have problem with the code where I need to set the tutor to get the list of subjects which are in String.

Here's the snippet of code in the servlet:

tutor m4 = new tutor();

String[] subj = request.getParameterValues("subject");

List<string>subjects = new ArrayList<string>(Arrays.asList(subj));

for(String subject : subjects){ //next() returned showed values<br/>System.out.println(subject);//no explicit return value<br/>// m4.setSubject(subject); //setSubject() returned null<br/>//m4.setSubjlist(subjects);<br/>m4.setSubjs((Subject) subjects);

I have tried various ways to set the subject at the class without avail.

The error message // shows that the tutor is not reading in the values

Here's how I did the setter at tutor class

public class tutor{<br/>private String tutorName;<br/>tutor subj;<br/>public tutor setSubject(String subject) {<br/>  return this.subj;<br/>  }

My question is how do I write the setter in tutor Class in order for the code to work in the Servlet. I am using Java EE7 and jdbc, 1.8 Java SE and Tomcat.

Try with the following code:

public class tutor{

        private String tutorName;

        tutor subj;

       

        public String getTutorName() {

            return tutorName;

        }

        public void setTutorName(String tutorName) {

            this.tutorName = tutorName;

        }

        public tutor getSubj() {

            return subj;

        }

        public void setSubj(tutor subj) {

            this.subj = subj;

        }           

}

Don't return the value from the set method, create a get method to return the value;
