Overview
I’ve been asked several times to explain the difference between injecting Spring beans with ‘@Resource’, ‘@Autowired’, and ‘@Inject’. While I received a few opinions from colleagues and read a couple of posts on this topic I didn’t feel like I had a complete picture.

clone() 方法
- 博客分类：
- Java
在应用开发过程中，我们可能会需要拷贝（copy）一个现有的对象，即得到一个新对象并希望其与现有对象封装完全相同的信息（属性值），主要是为了此后两者互不相干，修改其中的一个对象不会影响到另外一个。简单地引用变量间的赋值是不能解决问题的，因为并没有创建新对象；而自己编写代码先创建一个新对象，再将原始对象的属性一一复制过来也比较繁琐，且存在“浅度拷贝”问题；这种情况下，利用clone() 方法来实现对象拷贝不失为一种明智的选择。
Object类中的clone()方法专门提供拷贝当前对象的功能，其原型如下：
/**
* Creates and returns a copy ...
两种实现方法：
继承Thread类，
实现Runnable接口
Thread类是Runnable接口的子类
使用Runnable接口可以实现资源共享的目的
所有的线程操作都必须通过Thread类的start()方法启动
package org.fool.thread;
public class ThreadTest
{
public static void main(String[] args)
{
Thread thread1 = new Thread01();
Thread thread2 = new Thread(new Thread ...
