How to use an interface as a parameter when i try to use reflection in java

Question

I have an interface which is generic:

public interface DataTable < T > {

}

And I have a Factory class returning an instance of my class that implements DataTable<T>

public class DataTableFactory<T> {

    public DataTable<T> getInstance() { 
             return dataTableImpl();
    }
}

And another class named as list which has a method public void setDataTable(DataTable < T > dataTable)

Now i just want to invoke this method by using java reflection:

Helper helper = new Helper(operationsFile);
Class c = null;
c = Class.forName(helper.getClassName("list"));
Object t = c.newInstance();

Method methodSetDataTable = c.getDeclaredMethod("setDataTable", paramTypes);

In this example I couldn't find how to get paramTypes .

Answer 1

在没有看到setDataTable的方法声明的setDataTable ，我希望param类型只是DataTable.class 。
