Java accepts multiple numbers to sum output from the command line

• Design Ideas

1. Define an integer variable sum, which is used to receive and

2. Summing the command line numbers with a loop

3. Number of output parameters and the sum of parameters

Two • flowchart

Three • Program source code

public class Javaapparguments {
public static void Main (string[] args) {
int sum=0;//defines an int type variable sum as
System.out.println ("Number of parameters:" +args.length);//number of output parameters
for (String Arg:args) {
Sum=sum+integer.parseint (ARG);//convert to number sum

}
System.out.println ("sum=" +sum);//sum of output parameter numbers
}
}
