### Question:
TableCreator { public static void createTable(Class<?>... classes) { for (Class cl : classes) { DBTable dbTable = (DBTable) cl.getAnnotation(DBTable.class); if (dbTable == null) { System.out.println("db table of class : " + cl.getName() + " is required."); continue; } String tableName = dbTable.name(); if (tableName.length() < 1) { tableName = cl.getSimpleName().toUpperCase(); } List<String> columnDefs = new ArrayList<String>(); for (Field field : cl.getDeclaredFields()) { String columnName; Annotation[] annotations = field.getAnnotations(); if (annotations.length < 1) { continue; } if (annotations[0] instanceof SQLInteger) { SQLInteger sqlInteger = (SQLInteger) annotations[0]; if (sqlInteger.name().length() < 1) { columnName = field.getName().toUpperCase(); } else { columnName = sqlInteger.name(); } columnDefs.add(columnName + " INT" + getConstraints(sqlInteger.constraints())); } if (annotations[0] instanceof SQLString) { SQLString sqlString = (SQLString) annotations[0]; if (sqlString.name().length() < 1) { columnName = field.getName().toUpperCase(); } else { columnName = sqlString.name(); } columnDefs.add(columnName + " VARCHAR(" + sqlString.value() + ")" + getConstraints(sqlString.constraints())); } StringBuilder createCommand = new StringBuilder("CREATE TABLE " + tableName + "("); for (String columnDef : columnDefs) { createCommand.append("\n ").append(columnDef).append(","); } String tableCreate = createCommand.substring( 0, createCommand.length() - 1) + ");"; System.out.println("Table Creation SQL for " + cl.getSimpleName() + " is :\n" + tableCreate); } } }  static void createTable(Class<?>... classes);  }### Answer:
@Test public void testCreateTable() throws Exception { TableCreator.createTable(Member.class); }
