The Java implementation receives multiple numbers from the command line and outputs the results after summing.

The Java implementation receives multiple numbers from the command line and outputs the results after summing.

1 Design ideas:

(1) Create a class.

(2) The number of output parameters.

(3) defines the NUM and sum of int, which is used to store the sum of parameters and parameters respectively.

(4) A For loop argument is coerced into an int, and the converted parameter and sum are added, and the final result is recorded with Sum.

(5) Output sum.

2 Program Flowchart:

3 Source code:

Package CSXJ;
public class Csxj {
public static void Main (string[] args)
{
System.out.println ("Number of parameters" +args.length);
int num;//parameters that store integer types
int sum=0;//parameter's and
for (String Arg:args)//Loop
{
Num=integer.parseint (ARG);//cast string argument to int type
Sum=sum+num;
}
System.out.println ("Several numbers combined with" +sum);//Output

}
}
