Answer 1

Have a look at the parameters of Java's main method.
https://www.javatpoint.com/java-main-method
It takes a string array.

Note that sololearn Java playground is not interactive; you cannot pass command line arguments.

Answer 2

First, you need to change the following.
--public static void main(String[] args)--

String[] args is a command line argument, so the argument can only be passed at runtime. And this site, as far as I know, does not pass arguments at runtime. So you need to define a function or write variables directly.

Example:
public class Program
{
public static void main(String[] args) {
//Directly
String customerName="ABC";
System.out.println("Customer Name:" + customerName);

//call function
call("CDE",101);
}

public static void call(String customerName, int membershipCode){
System.out.println("Customer Name:" + customerName);
System.out.println("Membership code:" + membershipCode);
}
}
