Should the argument of the main method in java always be a string?I am a noobie in java

Question

main method in java

Answer 1

String args[], which is actually an array ofjava.lang.String type, and it's name is args here. It's not necessary to name it args always, you can name it strArrayor whatever you like
In Java args contains the supplied command-line arguments as an array of String objects.
In other words, if you run your program as java MyProgram one two then args will contain ["one", "two"].
If you wanted to output the contents of args, you can just loop through them like this...
public class ArgumentExample { public static void main(String[] args) { for(int i = 0; i < args.length; i++) { System.out.println(args[i]); } } }

Answer 2

Args always needs to represent an array of strings because that is what the operating system will pass it.
