注意：复制的消息让用户知道我发布了。

嗯...认为你的问题那是不行的。没有完全读完，抱歉。


用（int i = 0; i< args.length; i ++）{/ *声明total = 0之前*进行for循环* / total + = Integer.parse（args [i]）


这有帮助吗？

Um... Thought your problem was that didn''t work. Didn''t read completely, sorry.

Make a for loop with (int i = 0; i < args.length; i++) { /*declare total=0 earlier*/ total+=Integer.parse(args[i])

Does that help?
