第1题:
阅读下列函数说明和Java代码,将应填入(n)处的字句写在对应栏内。
【说明】
通常情况下,用户可以对应用系统进行配置,并将配置信息保存在配置文件中,应用系统在启动时首先将配置文件加载到内存中,这些内存配置信息应该有且仅有一份。
下面的代码应用了单身模式(Singleton)以保证Configure类只能有一个实例。这样,Configure类的使用者无法定义该类的多个实例,否则会产生编译错误。
include <iostream.h>
class Configure{
(1);
Configure(){}; //构造函数
public:
static Configure *Instance();
public:
int GetConfigureData(){return data;} //获取配置信息
int SetConfigureDate(int m_data)
{data=m_data; return data;} //设置配置信息
private:
static Configure* _instance;
int data; //配置信息
};
(2)=NULL;
Configure * Configure∷Instance()
{ if(_instance==NULL)
{ _instance=(3);
//加载配置文件并设置内存配置信息,此处省略
}
return (4);
}
void main()
{ Configure *t=NULL;
t=(5);
int d=t->GetConfigureData();
//获取配置信息后进行其它工作,此处省略
}
