Добавление в связующую таблицу (many to many) через JDBC?

MaxLich, public void addDevSkills(long id, long skillID) {
List skillsID = new ArrayList<>();
Statement statement = null;

String sql1 = "SELECT * FROM skills";
String sql2 = "INSERT INTO skills_developers VALUES (?,?)";
try (Connection connection = ApplicationJDBC.getConnection()) {
statement = connection.createStatement();
ResultSet rs = statement.executeQuery(sql1);
while (rs.next()) {
long i = rs.getLong("id");
if (skillsID != null) {
skillsID.add(i);
}
}
PreparedStatement preparedStatement = connection.prepareStatement(sql2);
Developer developer = new Developer();
for (Long sk_id : skillsID) {
if (sk_id == skillID) {
preparedStatement.setLong(1, developer.getId());
preparedStatement.setLong(2, sk_id);
}
}
} catch (SQLException e) {
e.printStackTrace();
}
}
