package database;
    
    import java.sql.Connection;
    import java.sql.DriverManager;
    import java.sql.ResultSet;
    import java.sql.SQLException;
    import java.sql.Statement;
    
    import javax.swing.JOptionPane;
    
    public class DataDemo {
        public DataDemo() {
            try {
                Class.forName("org.sqlite.JDBC");// load the JDBC driver
                Connection conn = DriverManager.getConnection("jdbc:sqlite:D:\\javaworkspace\\EmployeeData.sqlite");// get
    
                System.out.println("OK!Connect successfully!");
    
                Statement stmt = conn.createStatement();
                String query = "select * from EmployeeInfo";
                ResultSet rs = stmt.executeQuery(query);// execute query
                java.sql.ResultSetMetaData rsmd = rs.getMetaData();
    
                int intColumns = rsmd.getColumnCount();
    
                System.out.println("ResultSet中的列数--" + intColumns);
    
                for (int i = 1; i <= intColumns; i++) {
        
                    System.out.println(rsmd.getColumnLabel(i) + ((i == intColumns) ? "\n" : "\t"));
                }
    
                while (rs.next()) {
                    System.out.print(rs.getString(1) + " ");
                    System.out.println(rs.getString("name"));
                }
            } catch (ClassNotFoundException e) {
                JOptionPane.showMessageDialog(null, e);
            } catch (SQLException e) {
                JOptionPane.showMessageDialog(null, e);
            }
        }
    
        public static void main(String[] args) {
            new DataDemo();
        }
    }

> 注意：Java和sqlite数据库连接的时候，需要用到这个jar文件 [http://pan.baidu.com/s/1bPk5YI][http_pan.baidu.com_s_1bPk5YI] 还有，这个是示例中用到的数据库文件[http://pan.baidu.com/s/1i5nYJ3J][http_pan.baidu.com_s_1i5nYJ3J]
