从函数中获取项，然后在java中连接

public class Example {
    public static int getItem() {
        int item = 10; // 假设要获取的项是整数10
        return item;
    }

    public static void main(String[] args) {
        int result = getItem(); // 调用getItem方法获取项
        System.out.println("Item: " + result);
    }
}

import java.sql.*;

public class Example {
    public static void main(String[] args) {
        Connection connection = null;
        try {
            // 建立数据库连接
            String url = "jdbc:mysql://localhost:3306/mydatabase";
            String username = "root";
            String password = "password";
            connection = DriverManager.getConnection(url, username, password);

            // 执行数据库操作
            // ...

            // 关闭连接
            connection.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
