First, the idea of program design
The key to solve the problem is to convert the parameters into data types, the data type that is entered with the run configuration is of type string, so you need to convert the original string type to integer and then sum by using Integer.parse () or integer.valueof ().
Second, the Process flow chart
Third, the program source code
Letter 1605-2 Chen Yang 20160955
Package class5;
public class Sumofargs
{
public static void Main (string[] args)
{
int sum=0;//initialization sum result
System.out.println ("Number of Numbers:" +args.length);//number of statistical parameters
for (String Arg:args)
{
Sum=sum+integer.parseint (ARG);//Converts a parameter from a string type to an integral type and sums it with a for loop
}
System.out.println ("The sum of the numbers:" +sum);//Output summation result
}
}
Iv. Results
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.
