两个类,是模拟一个酒店管理,先输入管理者密码,再1是全部查询,2是个别查询,查不知道为什么,进入后总是要按两次2才能个别查询

if(getInfo().equals("2"))

welcome();
}
else

}这是第二个类class Counter
{
public static void main(String []args)
{

acc.adminlogin();
acc.welcome();
}
}
另外想问下如何关闭窗口?
多谢各位

多谢各位
改成如下:
void welcome()
{
notice();
String tempStr=getInfo();
if(tempStr.equals("1"))
{
all();
welcome();
}
else if(tempStr.equals("2"))
{
alone();
welcome();
}
else
{
}
}
