在终端中创建sqlite DB，但在Java程序（Mac）中连接到它

我正在写一个处理客户信息的基本程序。我在数据库部分遇到了一些问题（我从未用SQL或数据库编写过任何代码）。我的问题是。。。 如果我在Terminal中创建一个Sqlite数据库（b/c，似乎比在JAVA中更容易），并给它一个表，那么我如何在JAVA代码中连接到该数据库？我在tutorialspoint.com上看过Sqlite java教程，但似乎无法理解。真的很难受。我感谢所有的意见！ 注意：我想用对数据库的SQL调用替换名为“table”的数组。 这是我的密码：

public class Gui extends JFrame {   

 //Create the frame.
 public Gui() {

//General window commands
     Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
            int screenWidth = (int) screenSize.getWidth();
            int screenHeight = (int) screenSize.getHeight();
            final int programWidth = (int) ((double) screenWidth * 0.70);
            int programHeight = (int) ((double) screenHeight * 0.65);

     setBounds(screenWidth/9, screenHeight/10 /*or 90*/,programWidth, programHeight);
     setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        //Putting Data into the table
        //Will be replaced with SQL references

        //Table must be created after creation of Column Names and Data
            JTable table = new JTable(data, columnNames);

        //Create the scroll pane and add the table to it.
            JScrollPane scrollPane = new JScrollPane(table);
            table.setFillsViewportHeight(true);
