判断溢出方法:在执行完int newResult=result*10+tail语句后,紧接着进行逆运算result=(newResult-tail)/10,如果出现溢出,那么逆运算后result和newResult必然不相等,反之,如果没有溢出,则逆运算后result=newResult。 方法二: 判断溢出方法:采用long类型存储翻转后的数,再与 Integer.MAX_VALUE 和 Integer.MIN_VALUE ...
不管是toList()还是toSet()返回的都是咱最常用的集合类型,所以肯定可以add元素呀。 复制 @Test public void fun2(){List<Integer>list=new ArrayList<>();list.add(1);list.add(2);list.add(3);System.out.println(list.getClass());List<Integer>streamResultForList=list.stream().collect(toList())...

文档写出如果第一个参数集合c如果不支持add操作仍然抛出UnsupportedOperationException,就比如刚刚用一个数组List<Integer> list = Arrays.asList(a);此时的list不允许add操作,会抛出UnsupportedOperationException,同样的,此时再进行Collections.addAll(list, a);也是会抛出UnsupportedOperationException。
