@Entity
@Table(name="Student")
@org.hibernate.annotations.Entity(dynamicUpdate=true,dynamicInsert=true)
public class Student {
	@Id
	@GeneratedValue(strategy=GenerationType.AUTO)
	@Column(name="ID")
	private int id;
	
	@Column(name="NAME" )
	  
	private String name;
	@ManyToOne(cascade=CascadeType.ALL, targetEntity =Course.class,fetch=FetchType.LAZY)
	@JoinColumn(name="COURSEID")
	private Course course;
	
	public Student(){
		
	}
	
	public Student(int id, String name, Course course) {
		
		this.id = id;
		this.name = name;
		this.course = course;
	}
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public Course getCourse() {
		return course;
	}
	public void setCourse(Course course) {
		this.course = course;
	}
	@Override
	public String toString() {
		return "Student [id=" + id + ", name=" + name + ", course=" + course
				+ "]";
	}
	
	
	

}



@Entity
@Table (name="courses")
@org.hibernate.annotations.Entity(dynamicUpdate=true)
public class Course implements java.io.Serializable {
	
	private static final long serialVersionUID = 1L;
	
	@Id
	@GeneratedValue
	@Column(name="ID")
	private long id;
	@Column(name="name")
	private String name;

	public Course() {
	}

	public Course(String courseName) {
		this.name = courseName;
	}

	public Course(int id, String name) {
		this.id = id;
		this.name = name;
	}

	public long getId() {
		return id;
	}

	public void setId(long id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
	@Override
	public String toString() {
		return "Course [id=" + id + ", name=" + name + "]";
	}
	
}
