java – Why am I getting the warning :Class is a raw type. References to generic type Class<T> should be parameterized"?

I am getting warning in my ListActivity. The warning I am getting is shown below

• Class is a raw type. References to generic type Class<T> should be
parameterized

It is not creating any problems, but I would like to know why I am getting this warning and how to suppress it. See line which written within asterisks.

public class Menu extends ListActivity {

    String classes[]={"Second","example1","example2","example3","example4"}; 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setListAdapter(new ArrayAdapter<String>(Menu.this,android.R.layout.simple_list_item_1,classes));
    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        // TODO Auto-generated method stub
        super.onListItemClick(l, v, position, id);
        String cheese=classes[position];
        try{
        **Class ourclass= Class.forName("com.app1."+cheese);**
        Intent ourintent= new Intent(Menu.this,ourclass);
        startActivity(ourintent);
        }catch(ClassNotFoundException e){
            e.printStackTrace();
        }
    }
}

Class<?> ourclass = Class.forName("com.app1."+cheese);

Answer：

Class<?> ourclass= Class.forName("com.app1."+cheese);
