Question

New to the world of Java and I was wondering how to make a program that when run takes input in this form:

java ProgramName 1 2 3 4 5 

That is, it takes 1,2,3,4 and 5 as inputs for the program. I’m guessing that it will take this as a string and that somehow I will need to convert this string to individual numbers?

Answer 1

The parameter args in main is an array that contains the command-line arguments as strings. The following code will loop through the arguments and print them.

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

For more information, have look at the documentation.
