反射获取成员变量并使用练习1

public class ReflectDemo02 {
    public static void main(String[] args) throws ClassNotFoundException, NoSuchMethodException, IllegalAccessException, InvocationTargetException, InstantiationException, NoSuchFieldException {
        //获取Class对象
        Class<?> c = Class.forName("com.reflect_02.Student");

        //获取构造方法对象
        Constructor<?> con = c.getConstructor();
        Object obj = con.newInstance();
        System.out.println(obj);

        //获取成员变量对象
        Field nameField = c.getDeclaredField("name");
        nameField.setAccessible(true);
        nameField.set(obj,"旭旭宝宝");
        System.out.println(obj);

        Field ageField = c.getDeclaredField("age");
        ageField.setAccessible(true);
        ageField.set(obj,35);
        System.out.println(obj);

        Field addressField = c.getDeclaredField("address");
        addressField.setAccessible(true);
        addressField.set(obj,"东营");
        System.out.println(obj);
    }
