我帮你写了，上面是打印现在日期，后面是设置的．import java.util.Calendar;
class Demo
{

public static void main(String args[])
{
String year="1977";
String month="10";
String date="19";
String months[]={"jan","Feb","Mar","Apr","May",
"jun","JUly","Aug","Sep","Oct","Nov","Dec"};
Calendar calendar=Calendar.getInstance();
System.out.print("date: ");
System.out.print(months[calendar.get(Calendar.MONTH)]);
System.out.print(" "+calendar.get(Calendar.DATE)+" ");
System.out.println(""+calendar.get(Calendar.YEAR));

System.out.print("Time: ");
System.out.print(calendar.get(Calendar.HOUR)+":");
System.out.print(calendar.get(Calendar.MINUTE)+":");
System.out.println(calendar.get(Calendar.SECOND));
System.out.println("下面是设置日期：");
calendar.set(Calendar.YEAR,new Integer(year).intValue());
calendar.set(Calendar.MONTH,new Integer(month).intValue());
calendar.set(Calendar.DATE,new Integer(date).intValue());
System.out.print("update Date: ");
System.out.print(calendar.get(Calendar.YEAR)+"年");
System.out.print(calendar.get(Calendar.MONTH)+"月");
System.out.println(calendar.get(Calendar.DATE)+"日");
}
}
