"Unexpected type required class found type parameter Attack"

Question

this is my code (trying to write a copy constructor for my class): ``` public class ArgumentTree extends DelegateTree { public ArgumentTree() {super();} public ArgumentTree(ArgumentTree sourceTree) { super(); Attack atck = new Attack(); // I get the Error here more code.... } } ``` I am getting this error: ``` unexpected type required: class found: type parameter Attack ``` just to clarify: I don't want to make the code generic. I already know that the types I will use will be only GameArgument and Attack. Also, Attack has its own proper default constructor.

Accepted Answer

You are using actual class names as type variables. This doesn't make sense. Maybe you want something like

```
public class ArgumentTree extends DelegateTree<GameArgument, Attack>
```
