Open connection in try-with-resources - second resource depend on first

Question

I would like to use try-with-resources. I have two resources, where second depend on first. After initialize first, I need to execute method on first resources. Next I can initialize second resource. What can I do it?

try (First first = resource.get());
     --Here I need run method: first.connect(...);
     Second second = first.get())
     {
      ...
     }

You can nest try-with-resources, just like you can with normal try-blocks:

try (First first = resource.get()) {
    first.connect(...);
    try (Second second = first.get()) {
        // ...
    }
}
