Set data in a tabular format on jbuttons

Question

Table under which jbuttons to be displayed

I have to display data on a jbutton which is retrieved from a database(mysql) but due to different length of the strings involved the presentation looks bad and disordered. Is there a way to get the alignment.This is my code to set the data on the jbutton 'j' is the jbutton array

  j[check].setText(rs.getString(1)+" "+rs.getString(2)+" "+rs.getString(3)+"  "+rs.getString(4)+" "+ws+rs.getString(5)+" "+rs.getString(6)+" "+rs.getString(7));

I have given some spaces for some particular set of data but in most cases it goes bad.

Here are 2 cases in which the lengths are different

CSE201 Programming Fundamentals 3 Saritha V. SJT-401 A1 59
CSE201 Programming Fundamentals 3 Yokesh Babu SJT-402 A1 58

Now after the 3rd string(i.e after "CSE201 Programming Fundamentals 3") the lengths differ and formatting goes bad.

@sola if i give no spaces then the formatting would go even worse as some strings have a length of 10 and some may go upto 25. — harry4, Oct 22 '12 at 09:13
Could you please add an example of the desired output? I suspect you want to modify the strings so that they have the same length? — Viktor Seifert, Oct 22 '12 at 09:16
@ViktorSeifert i have made the edit and i think if i make their lengths equal then it would work — harry4, Oct 22 '12 at 09:20
Uhm I find this really suspect why are you displaying such lines of text on `JButtons`?? Surely a `JTable` will do? You can retrieve selected/clicked cells etc as needed — David Kroukamp, Oct 22 '12 at 10:31
@DavidKroukamp i used tabbed spaces and had uloaded the same but an edit was made. — harry4, Oct 22 '12 at 11:37
@HarshitSharaff I see, well as I said JButton not ment for that — David Kroukamp, Oct 22 '12 at 11:41
@HarshitSharaff: I still don't see why `JTable` wouldn't work, as @David suggests. — trashgod, Oct 23 '12 at 13:26

As kleopatra comments, you need to chose your desired layout. Absent a clear statement of what you mean by bad and disordered, consider these alternatives:

FlowLayout, the default for JPanel, will use the enclosed component's preferred size.
GridLayout will ensure that the enclosed components are the same size and large enough to accommodate the largest button. An example is shown here for a grid of JPanel instances each containing a JButton; note that the buttons are centered by default. As you want a single row with an arbitrary number of columns, use new GridLayout(1, 0).
BoxLayout with LINE_AXIS will attempt to use the preferred width of the enclosed components, as shown here.

Be sure to pack() the enclosing Window. If this is not helpful , please edit your question to include an sscce that exhibits any problem(s) you encounter.

Also consider `JToolBar`, illustrated [here](http://stackoverflow.com/a/11949899/230513). – trashgod Oct 22 '12 at 16:30
By bad and disordered i mean that the look and feel.Also the method you suggest would only order size of my buttons but the text in it differs. – harry4 Oct 23 '12 at 05:32
A button's preferred size is calculated by the UI delegate based on the size of the name in pixels. If you change the name at run-time, you can `validate()` the enclosing `Container` to recalculate the sizes and `repaint()` to refresh the display. – trashgod Oct 23 '12 at 13:16
