分頁顯示功能函數的核心?代碼主要參考思路

package org.utils;import java.util.List;import org.entity.Student;/*** * @author 24519* 分頁的工具類**/
public class PageUtils {//頁大小（每頁顯示多少條記錄）private int pageSize;//當前頁private int currIndex;//總記錄數private int totalCount;//總頁數private int totalPage;//每頁顯示的數據List<Student> sList;public int getPageSize() {return pageSize;}public void setPageSize(int pageSize) {this.pageSize = pageSize;}public int getCurrIndex() {return currIndex;}//設置當前頁public void setCurrIndex(int currIndex) {//判斷當前頁是否小于0，如果是，則默認第一頁if(currIndex<=0){this.currIndex = 1;}else{this.currIndex = currIndex;}}public int getTotalCount() {return totalCount;}//計算總頁數public void setTotalCount(int totalCount) {this.totalCount = totalCount;int pages = totalCount%pageSize==0?totalCount/pageSize:totalCount/pageSize+1;totalPage = pages;}public int getTotalPage() {return totalPage;}public void setTotalPage(int totalPage) {this.totalPage = totalPage;}public List<Student> getsList() {return sList;}public void setsList(List<Student> sList) {this.sList = sList;}}
