Question

I have been using this “logic” in C++ and VB with success, but am tied up in Java…
Simply put,

public void DataProviderExample(String user, String pwd, String no_of_links,
        String link1, String link2, String link3) {

for (int i=1;i<=no_of_links;i++) {
         String link = "link"+i;
         System.out.println(link);
}   

Now, if the variables link1, link2 and link3 have a value of “X”, “Y” and “Z” respectively, upon running this program, I get the following output –

link1
link2
link3

What I want is –

X
Y
Z

Any ideas?

You could use varargs:

public void DataProviderExample(String user, String pwd, String... links) {

for (String link : links) {
         System.out.println(link);
    }
}

...
DataProviderExample("user1", "password1", "X", "Y", "Z");
DataProviderExample("user2", "password2", "Q");

This way you can pass in the desired number of links, and the runtime automagically puts these into an array, which you can iterate over with a foreach loop.

With a plain array, calls would be more cumbersome (unless you already have the links in an array, of course):

public void DataProviderExample(String user, String pwd, String[] links) { ... }

DataProviderExample("user1", "password1", new String[] {"X", "Y", "Z"});
