在java反射中如何将c.newInstance()转为具体的类 而不是object?

Question

package test.action;

import test.entity.City;

public class Test {
public static void main(String[] args) {
City c=new City("111","江苏","22");
show(City.class);
}
public static void show(Class c1){
try {
Class c =Class.forName(c1.getName());
c.getConstructors();
try {
City o=(City) c.newInstance();
//这里如果不采用上述强转，该怎么得到City对象呢？

        } catch (InstantiationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    } catch (ClassNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

}

你要是直接用City类的话就可以不需要强转的，而如果是单纯用Class实例化的话则必须要强转

 City city ＝ City.class.newInstance();
