hi, I'm getting the error 'Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
at SumOfDigits.main(SumOfDigits.java:4)

the code is
public class SumOfDigits{
public static void main(String[] args){
int num = Integer.parseInt(args[0]);
int SOD = 0;
while(num!=0){
SOD=SOD+num%10;
num=num/10;
}
System.out.println("Sum Of Digits="+SOD);
}
}

First of all, enclose code in the proper code tags:

Dream.In.Code has a policy by which we prefer to see a good faith effort on your part before providing source code for homework assignments. Please post the code you have written in an effort to resolve the problem, and our members would be happy to provide some guidance. Be sure to include a description of any errors you are encountering as well.

Thank you for helping us helping you.

Second, your args array has a length of zero, there are no elements passed to the program when it is run.

When you run the program, make sure to pass runtime arguments to it.

java SomeClassNameHere 7 8 234 52345234 "hello"

If you are using an IDE, check their site or help section to see how to do this.

Your code's OK, just run it with argument, like
java SumOfDigits 1234
