如何用反射，調用帶參數的構造方法建立對象

1.建立一個實體對象,以及待參數的構造方法,getset自己補全

public class User {
    private String name;
    private String age;

    public User(String name) {
        this.name = name;
    }
}    
           

2.建立反射對象,調用構造方法建立對象

public static void main(String[] args) throws NoSuchMethodException, IllegalAccessException, InvocationTargetException, InstantiationException {
        Class<User> userClass = User.class;
        Constructor<User> constructor = userClass.getConstructor(String.class);
        User user = constructor.newInstance("張三");
        System.out.println(user);
    }
