如何捕获数据的SQLException？(例如,数据不存在)

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

public class SQLExceptionExample {

    public static void main(String[] args) {
        try {
            // 连接数据库
            Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/your_database", "username", "password");
            Statement statement = connection.createStatement();

            // 执行查询
            ResultSet resultSet = statement.executeQuery("SELECT * FROM your_table WHERE id = 1");

            // 检查数据是否存在
            if (resultSet.next()) {
                // 处理数据
                System.out.println("数据存在: " + resultSet.getString("column_name"));
            } else {
                // 处理数据不存在的情况
                System.out.println("数据不存在");
            }

            // 关闭资源
            resultSet.close();
            statement.close();
            connection.close();
        } catch (SQLException e) {
            // 处理SQLException
            System.out.println("捕获到SQLException: " + e.getMessage());
        }
    }
}
