利用反射创建对象

public class Reflection {
    public static void main(String[] args) throws Exception {
        Reflection reflection = new Reflection();
        System.out.println();
        Reflection.class.newInstance().test();
        System.out.println();
        Reflection.class.getConstructor().newInstance().test();
    }
    public void test(){
        System.out.println("测试成功！！");
    }
}
