Tip:
* 调用 Calendar 类的 add()方法计算 100 天后的日期
* 调用 Calendar 的 getTime() 方法返回 Date 类型对象
* 使用 FULL 格式的 DateFormat 对象，调用 format() 方法格式化 Date 对象 import
java.text.DateFormat; import java.util.Calendar; import java.util.Date; public
class demo16 { public static void main(String[] args) { Calendar
calendar=Calendar.getInstance(); //获取格式化的当前日期和时间
calendar.add(Calendar.DATE,100); //指定100天后，它与 DAY_OF_MONTH 是同义词 Date
date=calendar.getTime(); //返回Date类型对象 DateFormat
f=DateFormat.getDateInstance(DateFormat.FULL); //获取完全格式化的日期 //DateFormat.FULL
是完全指定，如 Tuesday、April 12、1952 AD 或 3:30:42pm PST。 String s=f.format(date);
//日期格式化 System.out.println(s); } }
输出结果:
