Batch insert using statement

int a= 100;
            try {
                        for (int i = 0; i < 10; i++) {
                            String insert = "insert into usermaster"
                                    + "("
                                    + "userid"
                                    + ")"
                                    + "values("
                                    + "'" + a + "'"
                                    + ");";
                            statement.addBatch(insert);
                            System.out.println(insert);
                            a++;
                        }
                      dbConnection.commit();
                    } catch (SQLException e) {
                        System.out.println(" Insert Failed");
                        System.out.println(e.getMessage());
                    } finally {
            
                        if (statement != null) {
                            statement.close();
                        }
                        if (dbConnection != null) {
                            dbConnection.close();
                        }
                    }
