JTable multiple instances - java

I have a JTable that gets data added to it from another JTable.
Now I want to switch between JTables according to the day selected in a JComboBox.
For example, if I choose Monday I add programs added to it then I select Tuesday from the JComboBox and a fresh JTable appears. If I go to Monday again the programs should still be there (until the program is closed).
How do I create multiple JTables (the JTable remains the same) for the days and let the info remain there until program closure?
Here is an example to show you what I mean:

Filtering the rows in an existing table seems easier. See Sorting and Filtering for how to create a RowFilter, instances of which can be added to a JComboBox and applied in the combo's action listener.

How to make filterable to jtable record using netbeans ide

There are many rows on above showing jtable. I want to filter record by short code. If I type short code like 1234 it should be display only short code 1234 associated row on jtable.
Thanks
You're going to have write the code...Start by checking out how to use tables, in particular sorting and filtering
The basic requirement would be to attach an ActionListener to both the field and button (you can do this from the form editor if you wish).
Within the actionPerformed event handler method, you need to create a RowFilter and apply it to the tables RowSorter.
A table can be configured to automatically create a row sorter by setting the autoCreateRowSorter property to true.
It's all explained nicely in the linked tutorials...

How to restrain checking single checkbox in multiple columns in Jtable

I am trying to implement a Jtable which includes three check-box tables like this:
Can you tell me how to set a single selection group of checkboxes which only allows 1 selected check-box in a single row at any time?
I know of nothing out-of-the-box for doing this. I´d have a TableModelListener check these columns every time a change is made and call setValueAt on the checkboxes as needed.

Load JList for cells of 1st column in JTable

Is there any way to load JList on the first column of JTable on click?
The table has zones in the 1st column (with multiple locations in every zone). I want to show zone locations to the user in a list, on zone click.
I am looking for it from 1 and half day. I don't want to put my code here because there is a lot of functionality in my table class.
One approach would be to add a ListSelectionListener to the table, as shown here, and update your ListModel according to the row selected. A JList listens to its own ListModel, so the update should be automatic.

How to add a new row to JXTable at runtime?

I am using JXTable to display a list of records.
When I click "Refresh" button, I want the JXTable to be refreshed to display the newly inserted records.
And also when I click "Add new Row" button, a new row must be added to JXTable.
How can I do these? I am unable to find any useful reference or samples. Please guide me.
It works the same as with a regular JTable, which is all explained in the table tutorial. But to answer your questions:
There is no need for a 'Refresh' button, unless the 'Refresh' button updates the TableModel. The moment you update your TableModel you should fire the appropriate events so that the JTable is aware of the changes made to the model. At that moment, the JTable will refresh itself automatically. If your TableModel extends from DefaultTableModel there are already methods available which take care of the events (like e.g. insertRow)
Inserting a row means adding a row to the TableModel + firing the appropriate events. If you use a DefaultTableModel, you can use the available API of the DefaultTableModel

Mutually Exclusive CellEditors in JTable

I currently have a problem whereby editing the contents of one cell in a JTable alters the content of another; two of the columns are mutually exclusive. They are both checkboxes.
At the moment, if I alter one cell, it isn't until the other is redrawn that it updates. Therefore, both cells in the row can be displayed as being selected at any one time. This can be overcome by calling updateUI(), but it is slow and not a generally great idea.
Has anyone got any tips or suggestions?
It sounds like you should be using a TableModelListener to listen for changes to the TableModel. When a checkbox is changed you will receive an update event and you would then update the other checkbox by using model.setValueAt(...). The model is responsible for notifying the view to repaint the cell.
