SimpleDateFormat顯示提取日期的一天的錯誤值

Question

我想單獨從日期時間字符串中提取日期和時間，但代碼顯示錯誤的日期。

代碼

String dateTime= "2015-12-10T14:00:00"; 
    SimpleDateFormat frm1 = new SimpleDateFormat("YYYY-MM-dd'T'HH:mm:ss"); 
    Date date = frm1.parse(dateTime); 
    SimpleDateFormat frm2 = new SimpleDateFormat("dd/MM/YYYY"); 
    String date1 = frm2.format(date); 
    System.err.println(date1); 
    SimpleDateFormat frm3 = new SimpleDateFormat("HH:mm"); 
    String time = frm3.format(date); 
    System.err.println(time); 

輸出

28/12/2015 
14:00

     Date date = frm1.parse(dateTime); 
     SimpleDateFormat frm2 = new SimpleDateFormat("dd/MM/yyyy"); 
     String date1 = frm2.format(date); 
     System.err.println(date1); 
     SimpleDateFormat frm3 = new SimpleDateFormat("HH:mm");
