Imitate the Javaapparguments.java example, write a program that receives multiple numbers from the command line, and then outputs the result after summing.

Design ideas

After running the configuration input number, it is a string type, with Integer.valueof (ARG), and after the conversion, it is added by the for loop and assigned to sum and then printed out.
