我正试图在Eclipse中做一个简单的控制台显示，我的时间和日期直接来自计算机。出于某种原因，年份显示只有3个字符，而不是4个字符，我不知道为什么。任何帮助都将是惊人的。这是代码：

public class InClass3 implements ActionListener
{
static int month, day, year, hour, minute;
public static void Display()
{
    int i;
    String []Date = new String[3];
    String []Hello = new String[3];
    String []Time = new String[3];
    Date();
    Time();
    for (i = 0; i < 3; i ++)
    {
        switch (i)
        {
        case 0:
            Hello[0] = "HELLO WORLD";
            Date[0] = month + "/" + day + "/" + year;               
            Time[0] = hour + ":" + minute;
            break;
        case 1:
            Hello[1] = "hello world";
            Date[1] = year + "." + month + "." + day;
            if (hour > 12)
            {
                hour = hour - 12;
                Time[1] = hour + ":" + minute + "pm";
            }
            else 
            {
                Time[1] = hour + ":" + minute + "am";
            }
            break;
        case 2:
            Hello[2] = "Hello World";
            Date[2] =  day + " " + month + " " + year;
            Time[2] =  hour + ":" + minute;
            break;
        default: System.out.println("Fatal error occured.  Please relaunch this application.");
        }
        System.out.println(Hello[i] + "n" + Date[i] + "n" + Time[i]);
    }
}
@SuppressWarnings("deprecation")
public static void Time()
{
    Date t = new Date();
    hour = t.getHours();
    minute = t.getMinutes();        
}
@SuppressWarnings("deprecation")
public static void Date()
{
    Date d = new Date();
    year = d.getYear();
    month = d.getMonth();
    day = d.getDay();
}
public static void main(String[] args) 
{
    Display();
}
@Override
public void actionPerformed(ActionEvent arg0) 
{
    // TODO Auto-generated method stub
}

}

这就是它输出的：

你好世界

2015年3月5日

下午14:47

你好世界

115.3.5

下午2:47

Hello World

5 3 115

下午2:47

我显然希望它能展示2015年，而不是115年。感谢您的真知灼见。
