Singleton和Double Check
首先看一段比较经典的代码：<div style="padding-right: 5.4pt; padding-left: 5.4pt; background: #e6e6e6; padding-bottom: 4px; width: 95%; padding-top: 4px;">public static Singleton getInstance()
{
if (instance == null) //0
{
synchronized(Singleton.class) {
if (instance == null)
instance = new Singleton();
}
}
return instance;
}
