java.lang.NullPointerException: null, I can not enter values into a class with an array of objects

hi I need to enter these values of different arraylist within a class to build a REST service, but it does not allow me to use object arrays to insert these values in my class so I do not want to be declaring "n" instances of my class to enter the data: AND I GET THE FOLLOWING ERROR

  

(: Servlet.service () for servlet   [operations.ups.edu.ec.finalproject.config.JerseyCo nfig] in context   with path [] threw exception [java.lang.NullPointerException] with   root cause

     

java.lang.NullPointerException: null           at operations.ups.edu.ec.finalproject.repository.imp.CoordinatesRepositoryValues.getCoordinates (CoordinatesRepositoryValues.java:32)   ~ [classes! /: 0.0.1-SNAPSHOT])

here my classes

CLASS OF WHOM I WISH TO GENERATE MICROSERVICE

public class Coordinates {
    int pointId;
    String longitud;
    String latitud;
    double distanceKm;
    boolean statusCalc;

    public Coordinates(){}

    public int getPointId() {
        return pointId;
    }

    public String getLongitud() {
        return longitud;
    }

    public String getLatitud() {
        return latitud;
    }

    public double getDistanceKm() {
        return distanceKm;
    }

    public boolean isStatusCalc() {
        return statusCalc;
    }


    public static class Builder{
        Coordinates coordinates= new Coordinates();

        public Builder pointId(int val){
            this.coordinates.pointId= val;
            return this;
        }

        public Builder longitud (String val){
            this.coordinates.longitud= val;
            return this;
        }

        public Builder latitud (String val){
            this.coordinates.latitud= val;
            return this;
        }

        public Builder distanceKm  (double val){
            this.coordinates.distanceKm= val;
            return this;
        }

        public Builder statusCalc (boolean val){
            this.coordinates.statusCalc= val;
            return this;
        }

        public Coordinates build() {
            return this.coordinates;
        }
    }
}

CLASE DONDE SE SE ENCUENTRAN LOS VALORES QUE DESEO INSERTAR 


@Service
public class CoordinatesPointsValuesRepository {


    public List id(){
        List <Integer> id = new ArrayList<Integer>();
        id.add(1);
        id.add(2);
        id.add(3);
        id.add(4);

        return id;
    }
    public List Longitud(){
        List <String> longitud = new ArrayList<String>();
        longitud.add("234567");
        longitud.add("345678");
        longitud.add("6543");
        longitud.add("54322");

        return longitud;
    }

    public List Latitud(){
        List <String> latitud = new ArrayList<String>();
        latitud.add("234asdN");
        latitud.add("345678SE");
        latitud.add("65OE43");
        latitud.add("54NE322");

        return latitud;
    }
    public List distanceKm(){
        List <Double> distanceKm= new ArrayList<Double>();
        distanceKm.add(12.3);
        distanceKm.add(2.2);
        distanceKm.add(5.5);
        distanceKm.add(8.0);

        return distanceKm;
    }
}
