If I had for example a class called Test and after compiling it, typing 'java Test 4 3' into the terminal would return 7 in the terminal.

Could someone explain how to do the above, I know how to make the method etc and how to make it work with arguments in the code, but how would I do it so it works like the eg above.

Thanks

You said that you've already know how to create the methods how to handle the arguments passed from the console. Can you show us the code that you've written. And tell us which part that is not working.

[stuckonjava]

No, I know how to make it in a normal program without the console but I have no idea how to do it with the console.

To create an executable class you have to define an entry point method. In Java this method have the following signature:

public static void main(String[] args) {
}

The args array will contains the arguments you pass when you are executing the class using java command. For example if you pass characters 4 and 3 as the arguments then this arrays will have these two numbers in it.

I'm a bit confused how I would write the rest.

public static void main(String args[]){
if (args.length() ==0)){System.out.println("No arguments");
int total =0;
for (int i =0; i < args.length(); i++){
total = total + args[i];
}
System.out.print(total);
}


Would this be along the correct lines?

In your posting history, I see a whole lot of threads you started and didn't return to. From the links given to you in this one, I can see you didn't even bother to read the responses.

Not the best way to get free help on a forum, that.
