Add values to existing JTable dynamically

Question

I've created a JTable using following way. This table has 5 columns and 4 rows. All 4 rows are empty in this status.

String[] columns = {"Emplotee ID","Name","Address","City","Salary"};

//Table that already have 4 empty rows
DefaultTableModel model = new DefaultTableModel(columns,4); 
JTable detail = new JTable(model);
JScrollPane scroll = new JScrollPane(detail);

Now I want to add values into those empty rows using String array. The GUI of this program has 5 JTextFields to get user input. When I enter values into JTextFileds and click Add button, all JTextFiled values get by String array named values.

String[] values = new String[6];
//When click addButton all textFiled data should go into table
addButton.addMouseListener(new MouseAdapter(){ 
    @Override
    public void mouseClicked(MouseEvent evt){
        values[0] = idField.getText(); //get JTextFields data into array 
        values[1] = nameField.getText();
        values[2] = addressField.getText();
        values[3] = cityField.getText();
        values[4] = salaryField.getText();

        //What now?
    }
});

I know I can use this to add new row into the table. But this is not the feature what I want.

DefaultTableModel newModel = (DefaultTableModel)detail.getModel();
newModel.addRow(values);

This is not what I want. I already have a JTable with 4 empty rows. I don't want to add another rows to it and just need to add values to existing rows. — Pahansith Gunathilake

Set contents of an existing table row with:

int row;
....
// make sure row is set to index of the table row
// you want to populate
for (int c=0; c<values.length; ++c)
    detail.setValueAt(values[c], row, c);

TableModel also has setValueAt method, if you prefer.

Thanks dude. I tried to look a built in method for doing above task. But this is also working for me.
