二，根据总的页数，当前页
这样的话构造函数应该写成:
public pagebean(int totalrows,int currentpage) {
  this.totalrows = totalrows;
  this.currentpage = currentpage;
  if(currentpage < 2)
   haspreviouspage = false;
  else
   haspreviouspage = true;
  if ((totalrows % pagerecorders) == 0) {
   totalpages = totalrows / pagerecorders;
  } else {
   totalpages = totalrows / pagerecorders + 1;
  }
  if (currentpage < totalpages) {
   hasnextpage = true;
   nextpage = currentpage + 1;
   pagestartrow = (currentpage - 1)*pagerecorders;
   this.pageendrow = pagestartrow + pagerecorders;
  } else if(currentpage == totalpages){
   pagestartrow = (currentpage - 1)*pagerecorders;
   this.pageendrow = totalrows;
   hasnextpage = false;
   nextpage = currentpage;
  }
  if(currentpage < 2){
   previouspage = currentpage;
   haspreviouspage = false;
  }else if(currentpage > 1){
   previouspage = currentpage-1;
   haspreviouspage = true;
  }
}
