Invoking a method in a different Class

I wanted to dos something like this, but as it turns out it does not work, any ideas how to fix it?

public class HelloWorld{
    public void method(){System.out.println("Hey");}

    public static void main(String []args){
        Test nTest = new Test();
        nTest.test();
    }

}
class Test{
    HelloWorld nHello = new HelloWorld();
    public void test{
        nHello.method();
    }
}

Try making your Test class public. I'm not an expert but explicitly giving the class the public Access level modifier should make that available to any other class ans any other file.

public class Test{
    HelloWorld nHello = new HelloWorld();
    public void test{
        nHello.method();
    }
}
