I am trying to call from my NrlData class, but the following line keeps giving me an error

```
public static class NrlMain {
    public static void main(String[] args) {
        NrlData nrlData = new NrlData();//No enclosing instance of type mProgram is accessible. Must qualify the allocation with an enclosing instance of type mProgram (e.g. x.new A() where x is an instance of mProgram).

```

any help with how i can resolve that would be great
