import java.util.List;

import org.bson.types.ObjectId;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

@Document(collection="courses")
public class Course {

    @Id
    private String _id;
    private String name;
    private String code;
    private String pass;
    private String lecture;
    private List<ObjectId> subjects;


    public String get_id() {
        return _id;
    }
    public void set_id(String _id) {
        this._id = _id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getCode() {
        return code;
    }
    public void setCode(String code) {
        this.code = code;
    }
    public String getPass() {
        return pass;
    }
    public void setPass(String pass) {
        this.pass = pass;
    }
    public String getLecture() {
        return lecture;
