Java Code Style Record

Example code:

1 classSolution {2     /**3      * @paramnums:a List of integers.4      * @return: A List of unique permutations.5      */6      PublicList<list<integer>> Permuteunique (int[] nums) {7         //Write Your code here8Arraylist<list<integer>> rst =NewArraylist<list<integer>>();9         if(Nums = =NULL) {Ten             returnrst; One         } A         if(Nums.length = = 0){ -Ts2.add (NewArraylist<integer>()); -             returnrst; the         } - Arrays.sort (nums); -arraylist<integer> list =NewArraylist<integer>(); -         int[] visited =New int[nums.length]; +          for(inti = 0; i < visited.length; i++) { -Visited[i] = 0; +         } A Helper (RST, list, visited, nums); at         returnrst; -     } -      Public voidHelper (arraylist<list<integer>> rst, list<integer> List,int[] visited,int[] nums) { -         if(list.size () = =nums.length) { -Rst.add (NewArraylist<integer>(list)); -             return; in         } -          for(inti = 0; i < nums.length; i++) { to             if(Visited[i] = = 1 | | (I! = 0 && Nums[i] = = Nums[i-1] && visited[i-1] = = 0)){ +                 Continue; -             } theVisited[i] = 1; * List.add (Nums[i]); $ Helper (RST, list, visited, nums);Panax NotoginsengList.remove (List.size ()-1); -Visited[i] = 0; the         } +     } A}

After 1.for, there are spaces;

After 2.if, there are spaces;

3. There are spaces before and after operators (+-*/, = =,! =,);

4. Comma semicolon followed by a space;

5.if for curly braces must not be omitted (--);

To do perfect ...
