java日期处理

1,
Calendar cd = Calendar.getInstance();
cd.setTime(new Date());
cd.add(Calendar.DATE, 1);//增加一天
 //cd.add(Calendar.MONTH, n);//增加n个月

2,java里的格式 yyyy-MM-dd HH:mm:ss
  oracle里的格式 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"><meta name="ProgId" content="Word.Document"><meta name="Generator" content="Microsoft Word 11"><meta name="Originator" content="Microsoft Word 11"><link rel="File-List" href="file:///C:%5CDOCUME%7E1%5Cuser%5CLOCALS%7E1%5CTemp%5Cmsohtml1%5C01%5Cclip_filelist.xml"><style></style>yyyy-MM-dd hh24:mi:ss
