Java日期类型与String的转换

1.String转Date

SimpleDateFormat sdf = new SimpleDateFormat("yyyymmdd");  
String date = "20100701"; 
try { 
     System.out.println(sdf1.format(sdf.parse(date)));
    } catch (ParseException e) {  
       e.printStackTrace(); /
    } 

2. Date转String

       Date date1 = new Date();   
        SimpleDateFormat sdf1 = new SimpleDateFormat("yyyy-MM-dd");  
        String str1 = sdf1.format(date1);
