我发现一个术语 原始物体。在搜索后,我发现一个原始的等级 是没有直接超级等级的类, 例如对象。 这是正确的吗?
另外,我怎样才能创造一个原始阶级, 因为每个爪哇阶级都从“对象”阶级中延伸。

您的“ 强” 无法创建基本等级 。
除了没有超级类的“对象 ” ( Object ) 之外, 每一类只有一个,只有一个直接的超级类( 单一继承 ) 。 如果没有任何其他明显的超级类, 每一类都隐含着“ 对象” 的子类。
班级可以来自从班级中衍生的班级,例如从班级中衍生的班级,最终来自最上层的班级“对象 ” ( Object ) 。 据说,这种班级是从继承链中从所有班级向上延伸至“对象 ” ( Object ) 。

您无法创建原始类 。 < number > 唯一的原始类是对象类 strong > 。
你们要申报的等级,将自动继承《讨拉特》的遗产。

how can I create a rimodal class as every Java class from Objects class. 我如何才能在每个 Java 类从对象类延伸出去时创建一个原始类 。
正如其他人回答的那样, 您无法创建原始类。 它已经由 Java 创建者以“ 强” 对象类 强” 的形式创建 。
