步骤4:在内部类中生成get和set方法 为了访问和修改内部类的属性,我们需要在内部类中生成get和set方法。对于属性value,我们创建一个名为getValue和setValue的方法。 publicclassOuterClass{// OuterClass的代码publicclassInnerClass{privateintvalue;// 内部类的私有属性valuepublicintgetValue(){returnvalue;// 返回valu...

The additional stipulation on constructors is, not surprisingly, that all constructors must create a set that contains no duplicate elements (as defined above). Note: Great care must be exercised if mutable objects are used as set elements. The behavior of a set is not specified if the value...
在PHP 中,虽然不像 Java 那样有明确的 Set 接口,但你可以使用数组来模拟集合的行为。PHP 的数组可以像集合一样使用,因为它支持添加、删除和检查元素的存在。PHP 8.1 及以上版本引入了 Set 类,但目前它并不是 PHP 标准库的一部分。因此,我们通常使用数组来实现集合的功能。
