This is more commonly written:
for (int i = 0; i < args.length; i++) {
}
Now, for the entirety try something like this:
int sum = 0;
for (int i = 0; i < args.length; i++ {
// This gives you the string out of the array
String tempString = args[i];
// This converts the String to an int
int currentIntValue = Integer.valueOf(tempString).intValue();
// This adds the current value to the sum
sum = sum + currentIntValue;
}
System.out.println("Sum: " + sum);
