java Date getYear()獲取年份問題

Calendar.getInstance().get(Calendar.YEAR);

JavaScript獲取年份需要加上1900

function getDateValue()
{
    var myweekday=""; 
    var year=""; 
    var mydate=""; 
    var mymoth=""; 
    var myyear=""; 
    mydate=new Date(); 
    myweekday=mydate.getDay(); 
    mymonth=mydate.getMonth()+1; 
    myday= mydate.getDate(); 
    myyear= mydate.getYear(); 
    year=(myyear > 200) ? myyear : 1900 + myyear; 
    if(myweekday == 0)weekday="星期日 "; 
    else if(myweekday == 1)weekday="星期一 "; 
    else if(myweekday == 2)weekday="星期二 "; 
    else if(myweekday == 3)weekday="星期三 "; 
    else if(myweekday == 4)weekday="星期四 "; 
    else if(myweekday == 5)weekday="星期五 "; 
    else if(myweekday == 6)weekday="星期六 "; 
    return "今天是 "+year+"年"+mymonth+"月"+myday+"日 "+weekday+" ";    
}
