I need to write a program that produces output from the command line arguments, i.e.:
java weekdays Monday Tuesday Wednesday Thursday Friday
Output would be:
Monday 6
Tuesday 7
Wednesday 9
Thursday 8
Friday 6
(the numbers on the right side represent the length of the string)
My program is:
1.public class weekdays {
2. public static void main(String[] args) {
3. for (int i=0; i<args.length; i++)
4. System.out.println(args[i] +"\t"+ length(args
));
5. }
6.}
When I compile, I get an error message on line 4:
The method length(String) is undefined for the type weekdays.
From what I understand, args is an array of strings taken from command line arguments.
So I believe, that I am asking for the length of the string, when I say: length(args[i]).
Also, the length() method is part of the String class.
I don't understand why I am getting the error message and how to fix it.
thanx,
Izzy.
