Java Utililty Methods JTable Row

boolean checkRow(DefaultTableModel table, List data, int row)
Checks if data could be written on the table starting from row.

String[] locations = data.get(1);
String[] time = data.get(2);
int rows = table.getRowCount();
int cols = table.getColumnCount();
int counter = 0;
for (int i = 0; i < locations.length; i++) {
 if (i - 1 >= 0) {
 counter += Integer.parseInt(time[i - 1].trim());
...

void clearAllRows(JTable table)
clear All Rows

DefaultTableModel tableModel = (DefaultTableModel) table.getModel();
int rowCount = tableModel.getRowCount();
for (int i = 0; i < rowCount; i++) {
 tableModel.removeRow(rowCount - i - 1);

boolean contains(int row, TableModel model)
contains

if (model == null) {
 return false;
if (row < 0) {
 return false;
return row < model.getRowCount();

void copyRows(JTable table)
copy Rows

 sb.append(getColumnData(table, iSelectedRow));
 sb.append("\n");
final StringSelection stsel = new StringSelection(sb.toString());
Toolkit.getDefaultToolkit().getSystemClipboard().setContents(stsel, stsel);

create DBXML File

String rootElement = docField;
String elementName = rowField;
StringBuffer toWrite = new StringBuffer("");

toWrite.append("<" + rootElement + ">");
Vector data = getRowsFromDatabase(con, 0, reuseConnection, driver, dsn, user, password, tableName,
 whereString, orderByString, groupByString);

Object createThrowableMessage(Throwable t)
create Throwable Message

JPanel panel = new JPanel(new BorderLayout(12, 12));

 list.remove(sortedRows[i]);
model.fireTableDataChanged();

void ensureRowCount(int count, JTable table)
Method checks if the row count is greater or equal to specified count, if not - it add a row

DefaultTableModel model = (DefaultTableModel) table.getModel();
int i, j;
for (i = table.getRowCount(); i < count; ++i) {
 model.addRow(new Object[table.getColumnCount()]);
 for (j = 0; j < table.getColumnCount(); ++j)
 table.setValueAt("", i, j);

boolean firstRowIsVoid(TableModel model)
first Row Is Void

boolean isVoid = true;
for (int colIndex = 0; colIndex < model.getColumnCount(); colIndex++) {
 if (model.getValueAt(0, colIndex) == null) {
 isVoid = true;
 } else {
 isVoid = false;
 break;
return isVoid;

int getModelRowAtPoint(JTable table, Point point)
get Model Row At Point

int row = table.rowAtPoint(point);
return rowToModelIndex(table, row);
