Question

有一个不知道哪里错的java程序 请高手们看下 老是提示说：无法从静态上下文中引用非静态变量。很郁闷

public class TestBubble
{
public static void main(String[] args)
{ Date[] days = new Date[5];
days[0] = new Date(2008, 01, 02);//老是这点报错
days[1] = new Date(2007, 02, 03);
days[2] = new Date(2005, 03, 04);
days[3] = new Date(2006, 04, 05);
days[4] = new Date(2007, 05, 06);
Bubblesort(days);
for(int i=0;i<days.length;i++)
{
System.out.println(days[i]);
}
}

public static Date[] Bubblesort(Date[] a)
{int len = a.length;
for(int i=len-1;i>=1;i--)
{for(int j=0;j<i-1;j++)
{if(a[j].compare(a[j+1])>0)
{
Date temp=a[j];
a[j]=a[j+1];
a[j+1]=temp;
}
}
}
return a;
}

class Date
{
int year,month,day;
Date(int y,int m,int d)
{
year=y;month=m;day=d;
}

public int compare(Date date)
{
return year>date.year? 1
:year<date.year? -1
:month>date.month? 1
:month<date.month? -1
:day>date.day? 1
:day<date.day? -1 : 0 ;

}
public String toString()
{
return "Year:Month:Day -- " + year + "-" + month + "-" + day;
}
}
}
一楼说的不行 我试过了 。

Answer 1

days[0] = new Date(2008, 01, 02);
这里肯定有错的啊
直接写成：days[0] ='2008-01-02'
就行了啊 --will

Answer 2

int里可以输入01？
