如何在Java Swing中检查SQL查询的批量执行是否成功？

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;

public class SQLBatchExecutionExample {
    public static void main(String[] args) {
        String url = "jdbc:mysql://localhost:3306/mydatabase";
        String username = "root";
        String password = "password";

        try (Connection connection = DriverManager.getConnection(url, username, password)) {
            String sql1 = "INSERT INTO users (id, name) VALUES (1, 'John')";
            String sql2 = "INSERT INTO users (id, name) VALUES (2, 'Jane')";
            String sql3 = "INSERT INTO users (id, name) VALUES (3, 'Bob')";

            PreparedStatement statement = connection.prepareStatement(sql1);
            statement.addBatch(sql2);
            statement.addBatch(sql3);

            int[] results = statement.executeBatch();

            for (int result : results) {
                if (result >= 0) {
                    System.out.println("SQL statement executed successfully. Rows affected: " + result);
                } else {
                    System.out.println("SQL statement execution failed. Error code: " + result);
                }
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
