Are there any methods that are used to get the data of the selected row? I just want to simply click a specific row with data on it and click a button that will print the data in the Console.
This question is related to
java
swing
jtable
tablemodel
The answer is

You will find these methods in it:
getValueAt(int row, int column)
getSelectedRow()
getSelectedColumn()
Use a mix of these to achieve your result.
Just simple like this:
tbl.addMouseListener(new MouseListener() {
@Override
public void mouseReleased(MouseEvent e) {
}
@Override
public void mousePressed(MouseEvent e) {
String selectedCellValue = (String) tbl.getValueAt(tbl.getSelectedRow() , tbl.getSelectedColumn());
System.out.println(selectedCellValue);
}
@Override
public void mouseExited(MouseEvent e) {
}
@Override
public void mouseEntered(MouseEvent e) {
}
@Override
public void mouseClicked(MouseEvent e) {
}
});
You can use the following code to get the value of the first column of the selected row of your table.
int column = 0;
int row = table.getSelectedRow();
String value = table.getModel().getValueAt(row, column).toString();
using from ListSelectionModel:
ListSelectionModel cellSelectionModel = table.getSelectionModel();
cellSelectionModel.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
cellSelectionModel.addListSelectionListener(new ListSelectionListener() {
public void valueChanged(ListSelectionEvent e) {
String selectedData = null;
int[] selectedRow = table.getSelectedRows();
int[] selectedColumns = table.getSelectedColumns();
for (int i = 0; i < selectedRow.length; i++) {
for (int j = 0; j < selectedColumns.length; j++) {
selectedData = (String) table.getValueAt(selectedRow[i], selectedColumns[j]);
}
}
System.out.println("Selected: " + selectedData);
}
});
if you want to get the data in the entire row, you can use this combination below
tableModel.getDataVector().elementAt(jTable.getSelectedRow());
Where "tableModel" is the model for the table that can be accessed like so
(DefaultTableModel) jTable.getModel();
this will return the entire row data.
I hope this helps somebody
