The difference in the behaviour is due to the fact that doinglist(some_array)returns a list ofnumpy.int64, while, doing the conversion via the string representation (or equivalently using thetolist()method) returns a list of python'sints: ...
Speaking about conversion way, it depends on why do you need yourList. If you need it just to read data. OK, here you go: Integer[] values = {1,3,7}; List<Integer> list = Arrays.asList(values); But then if you do something like this: ...

方法2:首先初始化一个与list大小相同的数组。然后通过循环将每个元素复制到数组中。 甘特图展示 接下来,我们用甘特图来展示上述代码的执行过程,以及各个步骤的使用时间。 2023-10-012023-10-012023-10-022023-10-022023-10-022023-10-022023-10-032023-10-03Creating ListUsing toArray()Manual LoopConversion Proces...
