从同一包中的另一个类访问JDBC方法

Question

I have a database class which imports java.sql.* and have following variables

Connection connect;
PreparedStatement statement;
ResultSet result;
public database() {} //constructor to connect to db [successful connection]

Now I create its instance in another class database db = new database(); , and I have to do something like this:

statement = connect.statement("sql query");

But to do this in another class, I have to do it like this:

db.statement = db.connect.db.statement("sql query");

It is showing error as well as it looks weird.

I think the possible solution could be to create local variables in another class

Connection connect = db.connect;
PreparedStatement statement = db.statement;

Which makes the database a useless class.

Answer 1

There was a misunderstanding in my approach

statement = connect.statement("sql query"); <--wrong statement

statement = connect.prepareStatement("sql query"); <--correct statement

so in another class it should be

db.statement = db.connect.prepareStatement("sql query");  <--worked perfectly
