} 
}

我不想要这些数据值程序里面的FIRSTNAMES，TOWNS，ROADS2，ROADS1，SURNAMES而是我想连接到mysql表。怎么做，任何人都可以帮助我。我想给JDBC连接到mysql。我不希望有我的班里面的人的数据值（）

我曾经写过[小教程作为答案]（http://stackoverflow.com/questions/2839321/java-connectivity-with-mysql/2840358#2840358）。你可能会觉得它很有用。 – BalusC 2010-08-21 14:44:51

你可以看看this入门教程。

网上有大量的教程，关于连接Java应用程序和MySQL。另一方面，如果你想进一步向前迈进一步，你可能想看看ORM工具，如Hibernate。它基本上允许您的Java应用程序连接到数据库（就像JDBC一样）。这种框架强大的优势在于，它允许您更改所使用的数据库，而无需对应用程序进行重大更改。更不用说它会自动将存储在数据库中的数据映射到对象，并且相反。
