查看David Crawshaw的网站,其中Java JDBC driver为SQLite。只需将他的JAR file添加到类路径并导入java.sql。*

他的测试应用程序将创建一个数据库文件,发送一些SQL命令来创建一个表,在表中存储一些数据,然后将其读回并在控制台上显示。它将在项目的根目录中创建test.db文件。

public class Test {
    public static void main(String[] args) throws Exception {
        Class.forName("org.sqlite.JDBC");
        Connection conn = DriverManager.getConnection("jdbc:sqlite:test.db");
        Statement stat = conn.createStatement();
        stat.executeUpdate("drop table if exists people;");
        stat.executeUpdate("create table people (name, occupation);");
        PreparedStatement prep = conn.prepareStatement(
            "insert into people values (?, ?);");

        prep.setString(1, "Gandhi");
        prep.setString(2, "politics");
        prep.addBatch();
        prep.setString(1, "Turing");
        prep.setString(2, "computers");
        prep.addBatch();
        prep.setString(1, "Wittgenstein");
        prep.setString(2, "smartypants");
        prep.addBatch();

        conn.setAutoCommit(false);
        prep.executeBatch();
        conn.setAutoCommit(true);

        ResultSet rs = stat.executeQuery("select * from people;");
        while (rs.next()) {
            System.out.println("name = " + rs.getString("name"));
            System.out.println("job = " + rs.getString("occupation"));
        }
        rs.close();
        conn.close();
    }
  }

SQLite的Java JDBC驱动程序位于David Crawshaw站点http://www.zentus.com/sqlitejdbc/将jar文件添加到类路径并导入java.sql。*,你应该很好。
