To handle this issue, we can use theArrayListclass. TheArrayListclass present in thejava.utilpackage allows us to create resizable arrays. 要解决此问题,我们可以使用ArrayList类。java.util包中存在的ArrayList类允许我们创建可调整大小的数组。 Unlike arrays, array lists (objects of theArrayListclass) can...
1、Arrays.asList转换过来的ArrayList和直接new出来的ArrayList是不一样的 两个集合类,一个是通过数组工具类的Arrays.asList转换而来的,一个是直接new出来的。打印出来的结果却不一样,一个是Integer[],一个是Object[]。最后第二个直接new出来的在类型转换时还报了异常。
