一个简单编程思想在php与java中的实现比较:日期类！

比较|编程

以前用PHP时写了一个简单的class，功能主要是解决，大量页面上需要显示下拉列表框选择年/月/日/周之类的。希望对大家学习PHP和java能有帮助。

php的实现如下：
getCurrentDate.class.php
/*
* 功能：生成下拉列表（年/月/日/周为当前值）
* 程序员：xiangli
* 日期：2003-01-19
*/

#---------------------------------------------------#
# 修改：2003-03-18                                  #
# 修改原因：添加了周的生成                            #
#-------------------------------------------------#

class getCurrentDate{
  var    $Years = 2002;
  var    $Months = 12;
  var    $Days = 31;
  var    $Weeks = 52;
  
    /*获得年的下拉列表*/
    function getCurrentYear()
    {
        for ($i = Date('Y'); $i >= $this->Years; $i--)
        {
            echo "{$i}年\n";
        }
    }

    /*获得月的下拉列表*/
    function getCurrentMonth()
    {
        for ($i = 1; $i Months; $i++)
        {
            ($i            if($i == date('m'))
                echo "{$m}月\n";
            else
                echo "{$m}月\n";
        }
    }

    /*获得日的下拉列表*/
    function getCurrentDay()
    {
        for ($i = 1; $i Days; $i++){
            if($i == date('d'))
                echo "{$i}日\n";
            else
                echo "{$i}日\n";
        }
    }
    
    /*获得周的下拉列表*/
    function getCurrentWeek()
    {
        for ($i = 1; $i Weeks; $i++){
            if($i == date('W'))
                echo "{$i}周\n";
            else
                echo "{$i}周\n";
        }
    }    
}
?>

调用如下：
includ("../public/getCurrentDate.class.php");
$getCurrentDate = net getCurrentDate();

=$getCurrentDate->getCurrentYear()?>
