Date和String之间的转化

//Date类型转换为String
Date now = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
String nowTime = sdf.format(now);
//String类型转换为Date
String s = "2008-01-15";
String[] a = s.split("[-]");
Date d = new Date(Integer.parseInt(a[0]),Integer.parseInt(a[1]),Integer.parseInt(a[2]));
