How to print enum description

Im creating a Java application, I used enum to create movie category. When I input MovieCategory.WAR I would like to see War movie(My description) instead of WAR. How is it possible? I tried MovieCategory.WAR.getDescription() but does't work.
public enum MovieCategory {
COMEDY("Comedy"), HORROR("Horror"), SCIFI("Sci-Fi"),
ACTION("Action movie"), ROMANTIC("Romantic"),
CLASSIC("Classic"), WAR("War movie");
private final String description;
MovieCategory(String description) {
this.description = description;
}
public String getDescription() {
return description;
}
}
public class MovieManager {
private List<Movie> movieList;
public MovieManager() {
this.movieList = new ArrayList<>();
movieList.add(new Movie("Simple movie", MovieCategory.WAR,"Testing description.",167,12));
(...)

The enum works correctly:
public static void main(String[] args) {
// Displays: Comedy
System.out.println(COMEDY.getDescription());
// Displays: COMEDY
System.out.println(COMEDY);
}
Or, maybe you want the toString method to use description?
public enum MovieCategory {
COMEDY("Comedy");
private final String description;
MovieCategory(String description) {
this.description = description;
}
public String getDescription() {
return description;
}
#Override
public String toString() {
return getDescription();
}
public static void main(String[] args) {
// Displays: Comedy
System.out.println(COMEDY.getDescription());
// Displays: Comedy
System.out.println(COMEDY);
}
}
UPDATE #3: It seems the issue is the JSON response. If you want the description to be returned, you can annotate the getDescription method wtih #JsonValue.
import com.fasterxml.jackson.annotation.JsonValue;
public enum MovieCategory {
WAR("War movie");
private final String description;
MovieCategory(String description) {
this.description = description;
}
#JsonValue
public String getDescription() {
return description;
}
#Override
public String toString() {
return getDescription();
}
public static void main(String[] args) {
// Displays: Comedy
System.out.println(WAR.getDescription());
// Displays: Comedy
System.out.println(WAR);
}
}

Unable to initialize an object through constructors in Java: Erroneous Compilation

This code below keeps throwing the following error:
Java Error Terminal Screen Snapshot
I've tried quite a few online fixes but they don't seem to be working.
My code is below and I've commented the error location(occurs in the driver main function)
NOTE: The code compiles properly if I change public static void main(String args[]) to public void main(String args[]) but when i run it, it throws the error "Change main to static void main". I'm a little stuck here.

You don't have a method called main, which is what it is looking for to run your program. Notice that when you create a template application for a java console application in intelliJ it has a method:
public static void main(string[] args) {
}
That needs to be there for your program to run.

How to get values from JSON pojo

The reason is that you're using a regular List interface for your list of networks instead of the generic version with the bounds for the expected type.
Try changing the field declaration from:
private List networks;
to
private List<Networks> networks;
While you're at it, it looks like you're using the regular List interface pretty much everywhere. You'll probably run into more issues if you don't convert them all to include the type you expect in the list.
Essentially, you're not providing enough information about the type of object you expect in the list for jackson to figure out what to populate it with. You can read more about generics here: http://docs.oracle.com/javase/tutorial/extra/generics/intro.html
EDIT:
It looks (from your comment) that you've already tried disabling checks for unknown properties, but try adding this annotation to your Networks class:
#JsonIgnoreProperties(ignoreUnknown = true)

How to add value from another class (java)

I have two classes: profesor and subject
public class Profesor {
private int numbClassroom;
public Profesor(int numbClassroom) {
this.numbClassroom = numbClassroom;
}
public int getNumbClassroom() {
return numbClassroom;
}
public void setNumbClassroom(int numbClassroom) {
this.numbClassroom = numbClassroom;
}
public String ToString(){
return "Number of classroom: "+numbClassroom;
} }
The second class is:
public class Subject{
String name;
Profesor lecturer = new Profesor();
Date yearOfStudy;
public void Dodeli(Profesor p){
??????
}}
I do not know how to add professor like a lecturer to a current subject

Like this? I don't see any problem.
public void Dodeli(Profesor p){
lecturer = p;
}

Profesor lecturer = new Profesor();
No need to instantiate lecturer. Just declare it. Then have getter/setter methods for it
Then you can assign Professor to Subject
Subject subj = new Subject("OOP"); //assuming you have corresponding constructor
subj.setLecturer(new Professor()); //or if you have existing prof object

Maybe require something like this : try to encapsulate your code
public class Professor {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
public class Subject{
private String name;
private Professor professor;
private int numbClassroom;
private Date yearOfStudy;
public int getNumbClassroom() {
return numbClassroom;
}
public void setNumbClassroom(int numbClassroom) {
this.numbClassroom = numbClassroom;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Professor getProfesor() {
return professor;
}
public void setProfesor(Professor profesor) {
this.professor = profesor;
}
public void Dodeli(){
System.out.println("Pofessor "+getProfesor().getName()+" is teaching "+getName()+" in Room NO :"+getNumbClassroom());
}
}
public class TestImpl {
public static void main(String arr[])
{
Subject subject = new Subject();
Professor professor = new Professor();
subject.setName("Biology");
professor.setName("MR.X");
subject.setNumbClassroom(1111);
subject.setProfesor(professor);
subject.Dodeli();
}
}
