How to get index value of a row in JTable?

[Shubham Rungta]

Hi,

Can anyone know how to get index value of a row in jtable.
I am trying to build a code where I want to add a row in between.
For this I need to know the index value of already inserted row.

Is it possible?


Thanks & Regards,

Welcome to the Ranch.

You don't add a row. You add the row data, typically using DefaultTableModel#addRow(Object[] rowData)
From the API docs for the above method

Adds a row to the end of the model.

If you want to insert add row data, at a specific index, you can use
DefaultTableModel#insertRow(int row,Object[] rowData)

Coming back to your question

For this I need to know the index value of already inserted row.

So how are you building your rows? If you start off with some default data, then the last row would be numberOfRows-1

Hi,

Thanks for reply

Suppose I am having 5 rows, now at index 3, I want to insert a new row ( each time this index value may change). How to get this index value.

Through insertRow() I can insert row at random position. But I am bother about this random position.

What I want is, when I select a row, I should get its index value. So by clicking on insert row button(which I'll be having on my form), I can add row at random index.

It is not random. The first paramter specifies the row index

Hi,

Thanks I got the solution.

Through " int insertRow=table_FM.getSelectedRow(); " I am able to get the index value of row.

Thanks Again
