Александр's questions

有必要在使用 Apache Poi 创建的文档中更改表格中的文本方向，告诉我该怎么做？

请告诉我，是否有时间间隔，例如

Period period = Period.of(5,3,15); 

有必要对指定的时间段应用 0.5 的系数，即将它分成两半，如何做到这一点？

上面的方法返回一个零区间，虽然周期的计算是正确的，告诉我错误是什么。

private Period kavendarVisl(DefaultTableModel dtm)
    {
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd.MM.yyyy");
        Period period = Period.ZERO;
        Period smalPeriod;
        for (int row=0;row<dtm.getRowCount();row++)
        {
            LocalDate ld1=LocalDate.parse(dtm.getValueAt(row,0).toString(),formatter);
            LocalDate ld2 = LocalDate.now();
            if (!dtm.getValueAt(row,1).toString().equals(""))
            {
                ld2=LocalDate.parse(dtm.getValueAt(row,1).toString(),formatter);
            }
            smalPeriod = Period.between(ld1,ld2);
            period.plus(smalPeriod);
            System.out.println(smalPeriod.getYears() + " - " + smalPeriod.getMonths());
        }
        System.out.println(period.getYears() +" - " +period.getMonths());
        return period;
    }

告诉我有一个表格

public class MainFrame extends JFrame {
    private int colThread=0;
    MainThread mt=new MainThread("Поток - 1");

    public MainFrame()  
    {
        setSize(300,300);
        setLocationRelativeTo(null);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JTable jTable=new JTable(20,4);
        jTable.setRowHeight(20);
        jTable.addMouseListener(new RightMouse());
        add(jTable);
    }
}

还有一个右键监听类

public class RightMouse extends MouseAdapter{

    @Override
    public void mousePressed(MouseEvent e) {
        // TODO Auto-generated method stub
        if (e.getButton()==MouseEvent.BUTTON3)
        {
            JPopupMenu popupMenu = new TableMenu(e);
            popupMenu.show(e.getComponent(), e.getX(), e.getY());
        }
    }

    private class TableMenu extends JPopupMenu
    {
        JMenuItem anMenu;

        public TableMenu(MouseEvent event) {

            this.anMenu = new JMenuItem("Увеличить ширину строки");
            add(anMenu);
            this.anMenu.addActionListener(new ActionListener() {
                @Override
                public void actionPerformed(ActionEvent e) {
                    if (event.getComponent() instanceof JTable)
                    {
                        JTable table = (JTable) event.getComponent();
                        try {
                            table.setRowHeight(table.getRowHeight() + 10);
                        }catch (IllegalArgumentException err)
                        {
                            table.setRowHeight(10);
                        }

                    }
                }
            });

            this.anMenu = new JMenuItem("Уменьшить ширину строки");
            add(anMenu);
            this.anMenu.addActionListener(new ActionListener() {
                @Override
                public void actionPerformed(ActionEvent e) {
                    if (event.getComponent() instanceof JTable)
                    {
                        JTable table = (JTable) event.getComponent();
                        try {
                            table.setRowHeight(table.getRowHeight() - 10);
                        }catch (IllegalArgumentException err)
                        {
                            table.setRowHeight(10);
                        }

                    }
                }
            });
        }   

    }
}

问题是我怎样才能改变某一行的高度，鼠标指针当前可以在该行上，而不是表中的所有行

请告诉我有一个表格

public class MainFrame extends JFrame {
    private int colThread=0;
    MainThread mt=new MainThread("Поток - 1");

    public MainFrame()  
    {
        setSize(300,300);
        setLocationRelativeTo(null);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JPanel jp = new JPanel();
        JButton jb=new JButton("Запустить поток");
        jb.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent arg0) {
                jb.setText("Перезапустить поток");
                colThread = colThread + 1;
                if (!mt.isInterrupted())
                {
                    mt.interrupt();
                }
                mt.start();             
            }           
        });
        jp.add(jb);
        add(jp);
    }
}

有一个流类：

public class MainThread extends Thread{
    private int summ;
    private String threadName;

    public MainThread(String threadName)
    {
        this.threadName = threadName;
    }   

    @Override
    public void run() {
        summ = 0;
        while(true)
        {
            summ = summ +1;
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            System.out.println(this.threadName + " " + summ);
        }
    }

}

和主要课程：

public class MainClass {
    public static void main(String[] args) {
        MainFrame mf = new MainFrame();
        mf.setVisible(true);
    }
}

问题是如何在单击按钮时重新启动线程的执行。以这种形式执行程序时，会出现错误，不过这是可以理解的，因为线程在工作，不清楚为什么interrupt()不起作用？

我正在尝试通过动态 Web 项目在 Eclipse 中创建一个 servlet

//@WebServlet("/hello_world")
public class FirstServlet extends HttpServlet {

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter pw=response.getWriter();

        pw.println("<html>");
        pw.println("<h1> Hello World </h1>");       
        pw.println("</html>");
    }

}

在 WEB-INF 文件夹中创建了以下 web.xlm 文件：

<?xml version="1.0" ecoding="UTF-8"?>
<web-app>
    <servlet>
        <servlet-name>FirstServlet</servlet-name>
        <servlet-class>FirstServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>FirstServlet</servlet-name>
        <url-pattern>/hello_world</url-pattern>
    </servlet-mapping>
</web-app>

Tomcat 连接到 8081 端口。我正在尝试对 URL http://localhost:8081/hello_world进行 servlet 调用，但事实证明需要通过项目名称调用它，而 web.xml 确实如此根本不工作。请告诉我有什么问题。

这种方式如何替换IDE中的部分代码，比如我决定进入

DefaultTableModel dtm=view.getZPJPanel().getPeriodDTM();

如何将整个代码中的所有内容都更改为dtm view.getZPJPanel().getPeriodDTM();

请告诉我，在上面的代码中，JDialog对象的左上角是放在屏幕中心的，我需要对象的中心在屏幕中心

public class RaschetDialog {
    public static void main(String[] args) {
        JDialog raschetDialog=new JDialog();
        raschetDialog.setModalityType(Dialog.ModalityType.APPLICATION_MODAL);
        raschetDialog.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);

        raschetDialog.setLocationRelativeTo(null);
        raschetDialog.setSize(600,400);
        raschetDialog.setVisible(true);
        raschetDialog.dispose();
        for (int i=0;i<1000;i++){
            System.out.println(i);
        }

    }
}

手动输入日期时出错

线程“AWT-EventQueue-0”中的异常 java.lang.ClassCastException：java.util.Date 无法转换为 java.util.Calendar

如何改进代码以便手动输入和使用下拉日历成为可能？

public class WordWorker {
    public static void main(String[] args) {
        Locale locale=new Locale("ru","RU");
        JFrame frame=new JFrame();
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        frame.setSize(300,300);
        UtilDateModel model=new UtilDateModel();
        Properties p=new Properties();
        p.put("text.today","Today");
        p.put("text.month","Month");
        p.put("text.year","Year");
        JDatePanelImpl datePanel=new JDatePanelImpl(model,p);
        JDatePickerImpl datePicker=new JDatePickerImpl(datePanel,new DateLabelFormatter());
        datePicker.setTextEditable(true);

        frame.add(datePicker,"Center");
        JButton jButton=new JButton("Кнопка");
        jButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                System.out.println(datePicker.getModel().getDay());
                System.out.println(datePicker.getModel().getMonth()+1);
                System.out.println(datePicker.getModel().getYear());
                System.out.println(datePicker.getModel().getValue());
            }
        });
        frame.add(jButton,"South");
        frame.setVisible(true);


    }
    private static class DateLabelFormatter extends JFormattedTextField.AbstractFormatter
    {
        private String datePattern="dd.MM.yyyy";
        private SimpleDateFormat dateFormatter=new SimpleDateFormat(datePattern);

        @Override
        public Object stringToValue(String text) throws ParseException {
            return dateFormatter.parseObject(text);
        }

        @Override
        public String valueToString(Object value) throws ParseException {
            if (value!=null)
            {
                Calendar cal= (Calendar) value;
                return dateFormatter.format(cal.getTime());
            }
            return "";
        }
    }
}

试图创建我自己的对话框

public class InformJDialog extends JDialog {
    private String title;

    public InformJDialog(String title) {
        this.title = "<html><font size=6 color=black>"+title;
        this.setSize(180,120);
        this.setUndecorated(true);
        this.setLocationRelativeTo(null);
        this.setLayout(new BorderLayout());
        this.setModal(true);
        JLabel jLabel=new JLabel(this.title);
        jLabel.setVerticalAlignment(SwingConstants.CENTER);
        jLabel.setHorizontalAlignment(SwingConstants.CENTER);
        this.add(jLabel,BorderLayout.CENTER);
    }
}

但是，与控制按钮一起，框架也被禁用，告诉我如何离开框架或创建自己的框架。谢谢你。

告诉我如何比较 ImageIcon 类的两个对象，如果它们包含相同的图片，则为真。谢谢你。

请告诉我，有一个序列化类，其中需要重写方法，例如toString，重写之前序列化的类后对象没有反序列化，我该如何解决这个问题？

有一个自定义类

public class Man implements Serializable{
    private HashMap<Object,Object> manMap;

    public HashMap<Object, Object> getManMap() {
        return manMap;
    }

    public void setManMap(HashMap<Object, Object> manMap) {
        this.manMap = manMap;
    }
}

有一些代码

Man man11=new Man();
        HashMap<Object,Object> dannie=new HashMap<>();
        dannie.put("Фамилия","Иванов");
        dannie.put("Имя","Иван");
        dannie.put("Отчество","Иванович");
        man11.setManMap(dannie);
        Man msn22=man11;

        dannie.put("Фамилия","Сидоров");
        dannie.put("Имя","Сидор");
        dannie.put("Отчество","Сидорович");
        man11.setManMap(dannie);

        System.out.println(msn22.getManMap().get("Фамилия").toString()+
                msn22.getManMap().get("Имя").toString()+
                msn22.getManMap().get("Отчество").toString());

请告诉我如何创建不随对象更改的对象的副本。需要使副本保持与更改前对象相同的状态吗？

告诉：

HashMap<String,String>data=new HashMap<>();
data.put("Имя","Вася");
data.put("Фамилия","Иванов");
HashMap<String,String>data11=data;
data.put("Имя","Петя");
System.out.println(data11.get("Имя"));

我怎样才能让第二次Map保存价值？

请告诉我有一个单元格范围，有必要使用 Apache POI 显示该范围的所有内部边界

CellRangeAddress region=new 
CellRangeAddress(7,9,0,4);
    RegionUtil.setBorderRight(BorderStyle.MEDIUM,region,sheet);
        RegionUtil.setBorderLeft(BorderStyle.MEDIUM,region,sheet);
        RegionUtil.setBorderBottom(BorderStyle.MEDIUM,region,sheet);
        RegionUtil.setBorderTop(BorderStyle.MEDIUM,region,sheet);

上面的代码显示了外部边框，但内部边框是必须的，我知道你可以为范围的每个单元格创建一个样式并遍历所有，但我认为有一个更合理的方式。谢谢你。

告诉我，在技术上是否可以使用 Apache Poi 将 ImageIcon 图像插入 Word 文档？

下午好，告诉我如何在编辑单元格中的数据后从单元格中获取值？在这个例子中，没有变化

public class PP extends JDialog {

请告诉我。JTable 表的列存在以下性质的问题，使用了一个编辑器，该编辑器又返回一个 JScrollPane 对象（或任何其他容器），上面有一个 JTextArea 对象，因此使用键盘进行编辑时，无法在 JTextArea 中输入任何值，因为它不是嵌套对象接收焦点（需要单击鼠标）。如何将焦点放在嵌套对象上？

public class PP extends JFrame {
    private String data[][]=new String[][]{{"","",""},{"","",""}};
    private String column[]=new String[]{"Фамилия","Имя","Отчество"};
    public PP() throws HeadlessException {
        super("Кадровая работа");
        this.setDefaultCloseOperation(EXIT_ON_CLOSE);
        this.setExtendedState(MAXIMIZED_BOTH);
        this.setVisible(true);
        JTable jTable=new JTable(data,column);
        jTable.setRowHeight(40);
        jTable.getColumnModel().getColumn(1).setCellEditor(new EditorJTA());
        this.add(new JScrollPane(jTable));
    }

    private class EditorJTA extends AbstractCellEditor
            implements TableCellEditor {
        private JTextArea editor = new JTextArea();
        private JScrollPane result=new JScrollPane(editor);

        @Override

            editor.setWrapStyleWord(true);
            editor.addKeyListener(new KeyAdapter() {
                @Override
                public void keyPressed(KeyEvent e) {
                    if(e.getKeyCode()==KeyEvent.VK_ENTER)
                    {
                        stopCellEditing();
                    }
                }
            });
            result.setBorder(new LineBorder(null, 0));
            return result;
        }

        @Override
        public Object getCellEditorValue() {
            return editor.getText();
        }
    }
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override

                new PP();
            }
        });
    }
}

美好的一天，告诉我，在我创建的表格中，在编辑单元格时，之前的值下降了，怎么办，当你用鼠标输入它时，之前的值在 Excel 中会保持什么样的状态？
