1.3、Arrays.asList()之后使用remove() 为啥使用了Arrays.asList()之后使用remove是错误用法,我们看一下asList()的源码就能知道了。Arrays.asList()返回的是一个指定数组长度的列表,所以不能做Add、Remove等操作。至于为啥是返回的是固定长度的,看下面源码,asList()函数中调用的new ArrayList<>()并不是我们常用...

elementData[--size] = null; // clear to let GC do its work } 如果直接对list调用了该方法,代码结果可能会不准确。例子如下:这段代码本想移除列表中全部值为2的元素,结果并没有成功。 Listlist = new ArrayList<>(Arrays.asList(1L, 2L, 2L, 4L, 5L)); ...
