帮帮新手！JTable？

Question

JTable jTable = new JTable(myTableModel);        jTable.addMouseListener(new MouseAdapter() {
            public void mouseClicked(MouseEvent e) {
                int row = jTable.getSelectedColumn();
                int col = jTable.getSelectedRow();
                Object obj = jTable.getValueAt(row, col);
                String value = obj == null? "":obj.toString();
                System.out.println(value);
            }
        });

Answer 1

sorry,有一个地方写错了。应该是：        JTable jTable = new JTable(myTableModel);        jTable.addMouseListener(new MouseAdapter() {
            public void mouseClicked(MouseEvent e) {
                int col = jTable.getSelectedColumn();
                int row = jTable.getSelectedRow();
                Object obj = jTable.getValueAt(row, col);
                String value = obj == null? "":obj.toString();
                System.out.println(value);
                Rectangle rect = jTable.getCellRect(row, col, false);
                jTable.repaint(rect);
            }
        });

Answer 2

faint，又忘记了。这两行是不用的：
             Rectangle rect = jTable.getCellRect(row, col, false);
                jTable.repaint(rect);

Answer 3

当鼠标单击JTable中的一行，如何得到这一行的值，并且把值放在数组里。怎么做呀？

Answer 4

jTable = new JTable(myTableModel);
        Object[] values = new Object[jTable.getColumnCount()];
        //上面这两行要放到方法外面定义。        jTable.addMouseListener(new MouseAdapter() {
            public void mouseClicked(MouseEvent e) {
                int col = jTable.getSelectedColumn();
                int row = jTable.getSelectedRow();
                Object obj = jTable.getValueAt(row, col);
                String value = obj == null? "":obj.toString();
                System.out.println(value);
                for (int i = 0; i < values.length; i++) {
                    values[i] = jTable.getValueAt(row, i);
                }
                
                
            }
        });

Answer 5

private String customOrder()
    {
        table1.addMouseListener(new MouseAdapter()
        {
            public void mouseClicked(MouseEvent e)
            {                int col=table1.getColumnCount();
                int row=table1.getSelectedRow();                Object obj=table1.getValueAt(row,col);
                String value=obj==null?"":obj.toString();
                System.out.print(value);
                
            }
        });
         return value;    }
这样为什么不对？

Answer 6

private String customOrder()
    {
        final String value;
        table1.addMouseListener(new MouseAdapter()
        {
            public void mouseClicked(MouseEvent e)
            {                int col=table1.getColumnCount();
                int row=table1.getSelectedRow();                Object obj=table1.getValueAt(row,col);
                value=obj==null?"":obj.toString();
                System.out.print(value);
                
            }
        });
         return value;    }

String value;
    private String customOrder()
        {
            table1.addMouseListener(new MouseAdapter()
            {
                public void mouseClicked(MouseEvent e)
                {
    
                    int col=table1.getColumnCount();
                    int row=table1.getSelectedRow();
    
                    Object obj=table1.getValueAt(row,col);
                    value=obj==null?"":obj.toString();
                    System.out.print(value);
    
                }
            });
             return value;
