效果如下：
代码：
package com.zp.test1; import java.util.ArrayList; import java.util.List; public class FenYeTest { static List<User> list=new ArrayList<User>(); static{ User user=new User("0","0"); User user1=new User("1","1"); User user2=new User("2","2"); User user3=new User("3","3"); User user4=new User("4","4"); User user5=new User("5","5"); User user6=new User("6","6"); User user7=new User("7","7"); User user8=new User("8","8"); list.add(user); list.add(user1); list.add(user2); list.add(user3); list.add(user4); list.add(user5); list.add(user6); list.add(user7); list.add(user8); } public FenYeTest() { } public static void main(String[] args) { } public static List<User> findUsers(int currentPage,int pageSize){ List<User> list1=new ArrayList(); int listLength=list.size(); if(currentPage<1){ currentPage=1; } int startIndex=(currentPage-1)*pageSize; int endIndex=startIndex+pageSize; if(endIndex>=listLength){ endIndex=listLength; } list1= list.subList(startIndex, endIndex); return list1; } } package com.zp.test1; import java.awt.BorderLayout; import java.awt.Color; import java.awt.Frame; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.util.ArrayList; import java.util.List; import java.util.Vector; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.ListSelectionModel; import javax.swing.table.DefaultTableCellRenderer; import javax.swing.table.DefaultTableModel; import javax.swing.table.JTableHeader; import javax.swing.table.TableCellRenderer; import javax.swing.JPanel; import javax.swing.JButton; public class JTableDefineTest extends JFrame{ private int currentPage=1; private int pageSize=2; private int lastPage; JTable table=null; DefaultTableModel dtm=null; JScrollPane jsp=null; JTableDefineTest jTableDefineTest=null; List list,list1; JButton button1 =null; public int getLastPage() { return lastPage; } public void setLastPage(int lastPage) { this.lastPage = lastPage; } public int getCurrentPage() { return currentPage; } public void setCurrentPage(int currentPage) { this.currentPage = currentPage; } public int getPageSize() { return pageSize; } public void setPageSize(int pageSize) { this.pageSize = pageSize; } public JTableDefineTest(){ list=FenYeTest.list; if(list.size()%pageSize==0){ setLastPage(list.size()/getPageSize()); }else{ setLastPage(list.size()/getPageSize()+1); } String[] columnNames = {"用户名","密码"}; dtm=new DefaultTableModel(columnNames, 0); table=new JTable(dtm); jsp = new JScrollPane(); jsp.setViewportView(table); getContentPane().add(jsp); setTitle("表格"); setBounds(100,100,500,500); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); showTable(currentPage); JPanel panel = new JPanel(); getContentPane().add(panel, BorderLayout.NORTH); JButton button = new JButton("首页"); button.addActionListener(new MyTable()); button.setActionCommand("首页"); panel.add(button); button1 = new JButton("上一页"); button1.addActionListener(new MyTable()); panel.add(button1); JButton button2 = new JButton("下一页"); button2.addActionListener(new MyTable()); panel.add(button2); JButton button3 = new JButton("末页"); button3.addActionListener(new MyTable()); panel.add(button3); setVisible(true); } public void showTable(int currentPage){ dtm.setRowCount(0);// 清除原有行 FenYeTest f=new FenYeTest(); setCurrentPage(currentPage); list1=f.findUsers(currentPage, pageSize); for(int row = 0;row<list1.size();row++) //获得数据 { Vector rowV = new Vector(); User user= (User) list1.get(row); rowV.add(user.getName()); //数据 rowV.add(user.getPass()); dtm.addRow(rowV); } // table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF); //关闭表格列的自动调整功能。 table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION); //单选 table.setSelectionBackground(Color.YELLOW); table.setSelectionForeground(Color.RED); table.setRowHeight(30); } public void init(){ } public static void main(String[] args) { new JTableDefineTest(); } class MyTable implements ActionListener { public void actionPerformed(ActionEvent e) { if(e.getActionCommand().equals("首页")){ showTable(1); } if(e.getActionCommand().equals("上一页")){ if(getCurrentPage()<=1){ setCurrentPage(2); } showTable(getCurrentPage()-1); } if(e.getActionCommand().equals("下一页")){ if(getCurrentPage()<getLastPage()){ showTable(getCurrentPage()+1); }else{ showTable(getLastPage()); } } if(e.getActionCommand().equals("末页")){ showTable(getLastPage()); } } } }
