How to include database values here....

 DefaultTableModel dm = new DefaultTableModel();
        dm.setDataVector(new Object[][]{
            {"119","Finbar", "John","Saunders","ja","ko","zh"},
            {"911","Roger", "Peter","Melly","en","fr","pt"}},
            new Object[]{"SNo.","First", "1","2","Native","2","3"});

I don't want hardcoded values. Please help me to get out of this. Any help from you will highly be appreciated. I am in a great need. Thanks in advance.
