打算要做一個工作總結(jié)平臺，考慮到要實現(xiàn)周工作總結(jié)的功能就得先把一年先按某周某周區(qū)分開來，查了查Api

采用了calendar類，并把最后分的結(jié)果傳到數(shù)據(jù)庫，

year        week          content

2005        1                 1月３日～１月９日

...              ...                .................... 

源碼如下(其中DB類是我用來實現(xiàn)數(shù)據(jù)庫連接用的)

import java.util.*;
import java.util.Date;
import java.sql.*;
import rkind.db;
public class shijian {
 public static void main(String args[]){
  int day,mon,year,week,dayofweek;  
  db base=new db();
  String content="";
  Calendar nova = Calendar.getInstance();
  
  Date d1=new Date(); 
  nova.setTime(d1);
  nova.set(2005,Calendar.JANUARY,1);
  //nova.add(Calendar.DATE,6);
  //day=nova.get(Calendar.WEEK_OF_YEAR );
  dayofweek=nova.get(Calendar.DAY_OF_WEEK  );
  while(dayofweek!=2){
  nova.add(Calendar.DATE,1);
  dayofweek=nova.get(Calendar.DAY_OF_WEEK  );
  }
  year=nova.get(Calendar.YEAR);
  //String sql=new String("insert into shijian(year,week,content) values('"+year+"','"+week+"','"+content+"')");
  //System.out.println("day+++:"+day);
  while(year==2005){ 
   week=nova.get(Calendar.WEEK_OF_YEAR );
   mon=nova.get(Calendar.MONTH)+1;
   day=nova.get(Calendar.DATE);
   
   content=mon+"月"+day+"日"+"~~ ";  
   
   System.out.print("第"+week+"周"+":  "+mon+"月"+day+"日");
   nova.add(Calendar.DATE,6);
   week=nova.get(Calendar.WEEK_OF_YEAR );
   mon=nova.get(Calendar.MONTH)+1;
   day=nova.get(Calendar.DATE);
   
   content+=mon+"月"+day+"日";
   try{
    String sql=new String("insert into shijian(year,week,content) values('"+year+"','"+week+"','"+content+"')");
    base.executeUpdate(sql); 
   }catch(Exception e){System.out.println(e);}
   
   System.out.println("~~~~"+mon+"月"+day+"日");
   
   
   
   nova.add(Calendar.DATE,1);
   week=nova.get(Calendar.WEEK_OF_YEAR );
   mon=nova.get(Calendar.MONTH)+1;
   day=nova.get(Calendar.DATE);
   year=nova.get(Calendar.YEAR);
   
   
  }
 
 } 
 
}

雖然功能上實現(xiàn)了，但是還有大量的重復(fù)代碼，和費語句，這就是沒有好好重視J2se的結(jié)果，沒辦法，

邊學(xué)J2EE邊看Se吧，：）
