Java,循环遍历结果集

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class ResultSetExample {
    public static void main(String[] args) {
        try {
            // 1. 导入JDBC驱动程序
            Class.forName("com.mysql.jdbc.Driver");

            // 2. 建立数据库连接
            Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydatabase", "username", "password");

            // 3. 执行SQL查询并获取结果集
            Statement stmt = conn.createStatement();
            ResultSet rs = stmt.executeQuery("SELECT * FROM mytable");

            // 4. 循环遍历结果集
            while (rs.next()) {

            // 5. 关闭资源
