如何检查哪个Swing组件作为参数传递？

Question

I have a method here (below) that, in itself, works very well. The problem is I want to change it's behavior based on which JTable is passed through the parameter.

For example, right now I have two JTables, table1 and table 2. I want to set up an if statement that says if (table == table1){...} else if (table == table2){...}

The problem is no matter what I try (comparing hash codes, comparing the e.source to the component, the source hashcode to the table1.hashcode() etc.) I can't get it to register when the table that is passed is in fact table1.

Is there a way to compare components in this way? (Again, confirming which JTable 'table' (the JTable passed in the parameters) is; 'table1' or 'table2'.

Here's my code:

 public TableCellEditor myCellEditor = new DefaultCellEditor(new JTextField()) {
    @Override
    public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) {
        delegate.setValue((editorComponent instanceof JTextField) ? null : value);
                myCellEditor.addCellEditorListener(
            new CellEditorListener() {
                public void editingCanceled(ChangeEvent e) {
                }

                public void editingStopped(ChangeEvent e) {
                    //if (table == table1){...} 
                }
            });
        return editorComponent;
    }

You need to know on what table did the even fired? Then use e.getSource(); If you want to see if tableX and tableY are similar then you need to write a Comparator . This example may help a bit. Generally Comparators are handy and quite easy to implement.

Try to avoid the

 new CellEditorListener() {
                public void editingCanceled(ChangeEvent e) {
                }

                public void editingStopped(ChangeEvent e) {
                    //if (table == table1){...} 
                }
            });

Instead create 2 CellEditors and assign your listener to each..

myCellEditor1.addCellEditorListener(listener);
myCellEditor2.addCellEditorListener(listener);


//Now by accessing e.getSource you know which celleditor fired!


CellEditorListener listener= new CellEditorListener() {
                public void editingCanceled(ChangeEvent e) {
                }

                public void editingStopped(ChangeEvent e) {
                   if (e.getSource()==myCellEditor1)
else if (e.getSource()==myCellEditor2)

                }
            });
