反射获取私有属性

package com.day14.fanshe;

import java.lang.reflect.Field;

public class Test {

	public static void main(String[] args) throws ClassNotFoundException, NoSuchFieldException, SecurityException,
			InstantiationException, IllegalAccessException {
		// TODO Auto-generated method stub
//		Student student = new Student();
//		Class<? extends Student> class1=student.getClass();
//		class1.getName();
//		System.out.println(class1.getName());

		//
//		Class<? extends Student> class1=new Student().getClass();
//		
//		try {
//			Class<?> class1=Class.forName("com.day14.fanshe.Student");
//			
//			Beans bean=(Beans) class1.newInstance();
//			
//		} catch (Exception e) {
//			// TODO: handle exception
//		}

		// 获取字节码对象
		Class class1 = Class.forName("com.day14.fanshe.Student");

		// 创建学生对象
		Object studObject = class1.newInstance();

		// 暴力反射获取属性
		Field filed = class1.getDeclaredField("name");

		// 设置反射时取消Java的访问检查，暴力访问
		filed.setAccessible(true);

		filed.set(studObject, "哈哈哈");
		Object nameObject = filed.get(studObject);
		System.out.println(nameObject);
	}
