scala> val s = "my string" val s: String = my string scala> s.init val res0: String = my strin As we can see in the example, by calling the init() method, we remove the last character of the String. If you just need to remove a single element, this solution will be fine....

如果该容器是vector、string或者deque,使用erase-remove idiom或者erase-remove_if idiom 如果该容器是list,使用list::remove或者list:remove_if成员函数 如果该容器是一个associative container,使用asso_con::erase成员函数或者remove_copy_if结合swap等方式 有一些比较特殊的容器具现,比如vector<bool>等,暂不考虑。 更...

String str = (String)var2.next(); if("e1".equals(str)) { list.remove("e1"); } if("e2".equals(str)) { System.out.println("element 2 fetched"); } } 为什么remove(e1)会导致无法获取e2? 当list.remove("e1")后,在while(var2.hasNext())时,返回结果将为false,因此当循环一次后Iterator...
