关于输入日期校验的问题

Question

我的代码大概是这么写的：
SimpleDateFormat formater=new SimpleDateFormat (yyyy/M/d);
try
｛formater.prase(变量year/变量month/变量day)；｝
catch
｛弹出错误窗口；｝
但发现prase不能有效检验我输入的字符。我输入零。但还是通过了…… 
请问有什么办法吗》？

javascript 的，参数未对应的text文本框对象 例如 你的form名为Form1 年份的名称为year1传入 Form1.year1
function checkDate(objYear,objMonth,objDay){
    var temp;
    var year,month,day;
    year = objYear.value;
    month = objMonth.value;
    day = objDay.value;
if(month.length==1){
objMonth.value ="0"+objMonth.value;
} if(day.length==1){
objDay.value ="0"+objDay.value;
}    var Str=year+month+day;
    if(!isPositiveInteger(objYear.value)){
      objYear.focus();
      
      objYear.select();
      alert(" \u5305\u542b\u975e\u6570\u5b57\u5b57\u7b26!"); //alert(" include some error char!");
      return false;
    }
    if(!isPositiveInteger(objMonth.value)){
      objMonth.focus();
      objMonth.select();
      alert(" \u5305\u542b\u975e\u6570\u5b57\u5b57\u7b26!"); //alert(" include some error char!");

      objDay.focus();

    else if(day>28 && day<31){
