getInstance
本词条缺少名片图，补充相关内容使词条更完整，还能快速升级，赶紧来吧！
getInstance是一个函数。在java中，可以使用这种方式使用单例模式创建类的实例，所谓单例模式就是一个类有且只有一个实例，不像object ob=new object();的这种方式去实例化后去使用。
GetInstance()
在java中，可以使用这种方式使用单例模式创建类的实例，所谓单例模式就是一个类有且只有一个实例，不像object ob=new object();的这种方式去实例化后去使用。
GetInstance()的用法
在写程序库代码时，有时有一个类需要被所有的其它类使用，但又要求这个类只能被实例化一次，是个服务类，定义一次，其它类使用同一个这个类的实例。
如果在每一个需要A的类中都声明一个A类的对象，那么会导致有N个类，每个A类的定义都不一样，但是这个A类是服务类，又只能定义一次，定义多个A类会导致A类有多个不同的内存地址。
解决这个矛盾的方法：
定义一个A的全局类对象，其它类共同使用这个实例化对象，这样保证A只实例化一次，使用extern A a声明一次，在源文件中定义A a即可；
但这种方式有一个问题，就是工程之间的访问，例如pro1中有A类，pro2需要使用A类，这样就不能完全保证A类只实例化一次，可能会出现pro1和pro2各实例化一次。
定义静态的实例化类(Singleton),如下：
static A* GetInstance()
static A* a = NULL;
if(a == null)
a = new A;
这样只要包含这个头文件，
A::GetInstance()-&…..
这样就保证只实例化一次。
GetInstance与new
对象的实例化方法，也是比较多的，最常用的方法是直接使用new，而这是最普通的，如果要考虑到其它的需要，如单实例模式，层次间调用等等。直接使用new就不可以实现好的设计，这时候需要使用间接使用new，即很多人使用的GetInstance方法。这是一个设计方式的代表，而不仅仅指代一个方法名。[1]
new的使用:
如Object _object = new Object()，这时候，就必须要知道可能会有第二个Object的存在，而第二个Object也常常是在当前的域中的，可以被直接调用的
GetInstance的使用:
在主函数开始时调用，返回一个实例化对象。此对象是static的，在内存中保留着它的引用，即内存中有一块区域专门用来存放静态方法和变量，可以直接使用，调用多次返回同一个对象。
两者区别对照:
大部分类(非抽象类/非接口/不屏蔽constructor的类)都可以用new，new就是通过生产一个新的实例对象，或者在栈上声明一个对象 ，每部分的调用用的都是一个新的对象。
getInstance是少部分类才有的一个方法，各自的实现也不同。getInstance在单例模式(保证一个类仅有一个实例，并提供一个访问它的全局访问点)的类中常见，用来生成唯一的实例，getInstance往往是static的。
