韩顺平老师 满汉楼 报表统计 柱状图

韩顺平老师讲的满汉楼餐饮管理系统里没讲报表统计这是我自己写的报表统计（柱状图）代码与大家分享（写的很不好请大家原谅）：import java.awt.BorderLayout;import java.awt.Color;import java.awt.FlowLayout;import java.awt.Font;import java.awt.Graphics;import java.awt.Image;import java.awt.Polygon;import java.awt.Toolkit;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import javax.swing.JButton;import javax.swing.JComboBox;import javax.swing.JFrame;import javax.swing.JLabel;import javax.swing.JPanel;import javax.swing.JScrollPane;import javax.swing.JTable;import javax.swing.JTextField;public class Test extends JFrame implements ActionListener {JPanel p1,p2,p3,p4,p5;JLabel p1_jl1,p3_jl1;JTextField p1_jt1;JButton p1_jb1,p4_jb1,p4_jb2,p4_jb3,p4_jb4;JComboBox p1_jc1;JTable jtable;JScrollPane jsp;BbModel bbm;BbPanelzhu bp1;BbPaneltiao bp2;public static void main(String[] args) {// TODO Auto-generated method stubTest t1=new Test();}public Test (){bbm=new BbModel();String []paras={"1"};bbm.query("select * from 报表where 1=? order by 年份", paras);bp1=new BbPanelzhu(bbm);//处理南面的p3=new JPanel(new FlowLayout(FlowLayout.LEFT));p4=new JPanel(new FlowLayout(FlowLayout.RIGHT));p4_jb1=new JButton("条形图");p4_jb1.addActionListener(this);p4_jb2=new JButton("柱状图");p4_jb2.addActionListener(this);p4.add(p4_jb1);p4.add(p4_jb2);p5=new JPanel(new BorderLayout());p5.add(p3,"West");p5.add(p4,"East");this.setLayout(new BorderLayout());this.add(p1,"North");this.add(bp1,"Center");this.add(p5,"South");this .setSize(1200,550);this.setLocation(200, 200);this.setVisible(true);this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);}@Overridepublic void actionPerformed(ActionEvent e) {}}//柱状图class BbPanelzhu extends JPanel{BbModel b1;int heig;int wid;public BbPanelzhu(BbModel bb){b1=bb;int a=Integer.parseInt((String)b1.getValueAt(0, 1));System.out.println(a);this.setBackground(Color.black);}public void drawZhu(Graphics g,int x,int y){g.setColor(Color.white);//画六边形int []x1={x,x+15,x+38,x+55,x+40,x+20};int[] y1={y,y-10,y-10,y-2,y+6,y+6};Polygon polygon1=new Polygon(x1,y1,6);g.fillPolygon(polygon1);//画左边四边形int []x2={x,x+20,x+20,x};int []y2={y,y+6,heig,heig-5};Polygon polygon2=new Polygon(x2,y2,4);g.fillPolygon(polygon2);//画中间矩形g.setColor(new Color(192,192,192) );g.fillRect(x+20, y+6, 20, heig-(y+6));//画右边四边形g.setColor(new Color(128,128,128) );int []x3={x+40,x+55,x+55,x+40};int []y3={y+6,y-2,heig-8,heig};Polygon polygon3=new Polygon(x3,y3,4);g.fillPolygon(polygon3);//画柱状图边线g.setColor(Color.black);g.drawLine(x, y, x+15, y-10);g.drawLine(x+15, y-10, x+38, y-10);g.drawLine(x+15, y-10, x+38, y-10);g.drawLine(x+38, y-10, x+55, y-2);g.drawLine(x+55, y-2, x+40, y+6);g.drawLine(x+40, y+6, x+20, y+6);//g.drawLine(x+20, y+6, x, y);g.drawLine(x, y, x, heig-5);g.drawLine(x, heig-5, x+20, heig);g.drawLine(x+20, heig, x+20, y+6);//g.drawLine(x+40, y+6, x+40, heig);//g.drawLine(x+40, heig, x+55,heig-8);g.drawLine(x+55, heig-8, x+55, y-2);g.drawLine(x+20, heig, x+40, heig); }public void paint(Graphics g){super.paint(g);heig=(this.getHeight()-100)/10*10;wid=this.getWidth()-100;//画网格g.setColor(new Color(0,128,64));//画竖线（y）for(int i=0;i<this.getWidth();){g.drawLine(i, 0, i, this.getHeight());i=i+10;}//画横线(x)for(int j=0;j<this.getHeight();){g.drawLine(0, j, this.getWidth(), j);j=j+10;}//画坐标轴g.setColor(Color.white);//竖轴(y)g.drawLine(100, 100, 100, heig);//横轴(x)g.drawLine(100, heig, wid, heig);//竖轴数字及标签(y)for(int i=heig,j=0;i>100;){g.drawLine(100, i, 105, i);g.drawString(j+"", 70, i);j=j+30;i=i-30;}//画日期(x)及柱体for(int i=100,j=2000,k=0;i<wid;){if(k<b1.getRowCount()){//画柱体及数字g.setColor(new Color(0,255,0));int b=Integer.parseInt((String)b1.getValueAt(k, 1));g.drawString(b1.getV alueAt(k, 1)+"", i+30, heig-b-20);this.drawZhu(g,i+15,heig-b);}//画年g.setColor(Color.white);g.drawString(j+"年", i+20,this.getHeight()-80 );j=j+1;i=i+70;k=k+1;System.out.println(b1.getRowCount()+"aaaa");}//标题g.setColor(Color.BLUE);g.setFont(new Font("楷体",Font.BOLD,20));g.drawString("2010年至2014年销售柱状图如下：(单位：万元)", this.getWidth()/2-250, 100);System.err.println(this.getWidth()/2);}}。
