这就是我现在所拥有的

//sq lite driver
        Class.forName("org.sqlite.JDBC");
        //database path,if it's new data base it will be created in project folder
        con = DriverManager.getConnection("jdbc:sqlite:mydb.db");

         Statement stat = con.createStatement(); 

        stat.executeUpdate("drop table if exists weights");

        //creating table
       stat.executeUpdate("create table weights(id integer,"
       + "firstName varchar(30)," + "age INT," + "sex varchar(15),"
       + "weight INT," + "height INT,"
       + "idealweight INT,primary key (id));");

现在我应该把这个语句[“：memory：”]放在内存中存储我的数据,数据应该保存直到我删除它.

谢谢
