Hi, Example program reads all the parameters entered by user and then calculate the sum of all.

Here is the full code example:

public class SumAll
{
  public static void main(String args[]) {
  int sum=0;
  for(int i=0;i<args.length;i++)
  {
     int val = Integer.parseInt(args[i]);
     sum = val+sum;
  }
  System.out.println(sum);
  }
}

You can run the program like this:

D:\1>javac SumAll.java

D:\1>java SumAll 1 2 3 4 5 6
21

D:\1>

Thanks
