public class PagBean {
private int curpage ;//当前页
private int totalpage ;//总页数
private int perpage = 10 ;//每页显示的条数

public PagBean(){}

public void setTotalpage(int value){
this.totalpage = value ;
}
public void setStartrow(){

}
public void setCurpage(int value){
this.curpage=value;
}
public void setNextpage(){

}
public void setPrepage(){

}
public int getTotalpage(ResultSet rs)throws Exception{
while(rs.next()){
totalrows++ ;
}

if(totalrows%perpage==0)
totalpage = totalrows/perpage ;
else
totalpage = totalrows/perpage + 1;
return totalpage ;
}
public int getStartrow() {
startrow = (curpage-1)*perpage+1;
return startrow ;
}
public int getCurpage(){
return curpage ;
}
public int getNextpage(){
nextpage =curpage +1 ;
return nextpage ;
}
public int getPrepage(){
prepage =curpage - 1 ;
return prepage ;
}
