JTable add 2 mini button into a cell - java

I wanted to know how to add 2 small button into a cell. This is used for 'Quantity' column in my jtable.
I want to do as the image above, user are allowed to edit the number inside or clicking add or minus the number, how do I do it?


The two arrows are part of a component called a Spinner. You can use a JSpinner to create textbox and use the SpinnerNumberModel to allow it to use numerical values:
JSpinner spinner = new JSpinner();
spinner.setModel(new SpinnerNumberModel());
You can read more about spinners in the Java documentation
To add it to a table, you will need a custom class which extends DefaultCellEditor. A few examples can be found here:
Is there a convenient way to use a spinner as an editor in a Swing JTable?

Editable cell and growable Jtable Implementation

I have a JTable with Customized CellRenderer and CellEditor, Intially the table is loaded with
a list of values Say with 12 rows and 5 colums, I have a JTextField at the top of the table in which I applied KeyListener and made the Textfield to display like a JComboBox with a list of values as soon as first 3 characters typed in that field, eg. Typing 'met' will display all the medicine names starting with "met", now what I want to do is I have to Implement that Textfield into the Jtable's last row's 2nd column Say 13th row in the situation I mentioned above. and after selecting any 1 medicine from the list of displayed value the JTable could Add a row dynamically and insert a new row with that search textfield, Please Suggest me an Idea and Code for this, also guide me how to apply cellrenderer and celleditor for a particular cell(Cell which contains the dynamic search textfield)...
Thanks a lot in Advance :)

Kindly let us assume jTable2 be your JTable variable name and TextField be your JTextField variable name. Then use the following code with the keylisterner of the text field to get what is wanted:-
javax.swing.table.DefaultTableModel dft= (javax.swing.table.DefaultTableModel)
jTable2.getModel();
jTable2.setModel(dft);
dft.addRow(new Object[1]);
jTable2.setValueAt(TextField.getText(),jTable2.getRowCount()-1,1);

How to assign the auto complete text field to JTable cell?

I have created one Class for auto complete text fields.
I want to use that Class and try to include my JTable cell fields, but it won't display.
Please advice

you can to use AutoComplete JComboBox / JTextField
put this JComboBox / JTextField to the JTable as Renderer and Editor

(Assuming I understand the question)
You need to wrap your editor in TableCellEditor. Have a look at Using Other Editors an example.
Once you have it set up, you need to register the editor with the table.
One way is to register the editor with the column in question via the TableColumnModel
table.getColumnModel().getColumn(indexToColumnInQuestion).setCellEditor(tableCellAutoCompleteEditor);

Create a numeric text box in java Swing with increment and decrement buttons

How can I create a numeric text box in java swing , which has two buttons (up and down) which increments and decrements the value in the text box respectively. Also this text box must be editable with ONLY NUMERIC VALUES. Something like this
I tried by placing two buttons near a text box and manually doing the operation on button click.
Is there any other method in which I can do this in a better way and achieve a similar result as the first image.
Thanks :)

Use JSpinner
How to use Spinners in java
Based on your comment:
SpinnerModel model = new SpinnerNumberModel(9.9, 1, 15, 0.1);
JSpinner spinner = new JSpinner(model);

JSpinner need for allows numeric input only, required some hack for that in its Model, but your 2nd. picture looks like as two JButtons (with JButton#setFocucPainted(false)), and one JFormattedTextField with number Format, with min/maxDecimalPaces, with roundingMode
myDoubleFormat.setMinimumFractionDigits(2);
myDoubleForma.setMaximumFractionDigits(2);
myDoubleForma.setRoundingMode(RoundingMode.HALF_UP);
then Action from JButton will be
myFtdTextField.setValue(((Number) myFtdTextField.getValue()).doubleValue() +/- 0.1)

Inserting radio buttons in a DefaultTableModel

I have a 2D array of objects which needs to be displayed in a table through a table model class which extends a DefaultTableModel. In addition to the columns needed to accommodate the data included in this array, I would like to add an extra column with radiobuttons, in order to enable the user to make a selection. As table model accepts only arrays of objects or vectors, how should I add radio buttons?

By default, JTable infers how to render and edit entries based on the entry's class, as discussed in the tutorial article Editors and Renderers. In this example, a checkbox allows multiple selections in a column. Substituting a radio button and using a ButtonGroup would accommodate a unique selection.
