Course Assignment 01: Imitate the Javaapparguments.java example, write a program that receives multiple numbers from the command line, and then outputs the result after summing.

1, design ideas:

Starting with the Javaapparguments.java example, this example prints the parameters, defines the sum of the numbers as the integral type of the storage unit, and then converts the string of the input parameter to an integer, then the sum, and the final output.

2, Program Flowchart:

3, source program code:

1  Packagedemo;2  3  Public classShuzisum {4  5      Public Static voidMain (string[] args) {6         //TODO auto-generated Method Stub7System.out.println ("Number of parameters:" +args.length);8  9           intsum = 0;//defines the number andTen           intNum;//Storing numbers One               for(String Arg:args) { ANum=integer.parseint (ARG);//convert strings to numbers -Sum+=num;//finding the sum of numbers -               } theSystem.out.println ("Sum of the Numbers:" +sum);//Output Results -     } -}

4, Results:
