Answer 1

You need to add PreRemove function ,in the class where you have many object as attribute e.g in Education Class which have relation with UserProfile Education.java

private Set userProfiles = new HashSet(0);

@ManyToMany(fetch = FetchType.EAGER, mappedBy = "educations")
public Set getUserProfiles() {
    return this.userProfiles;
}

@PreRemove
private void removeEducationFromUsersProfile() {
    for (UsersProfile u : usersProfiles) {
        u.getEducationses().remove(this);
    }
}
