I would like,as the title suggests, to be able to get all the values in an ID column from a JTable without the user actually selecting a row (and thus ID).Lets say there are two results in the JTable, that means there are two items in the ID column. Is there a way that I extract these values automatically.
Much depends on your goal, but you can
Traverse the TableModel
, invoking getColumnClass()
for each column; use getValueAt()
to examine the value for a particular row.
DefaultTableModel model = new DefaultTableModel(); … for (int col = 0; col < model.getColumnCount(); col++) { Class type = model.getColumnClass(col); }
Use the methods of DatabaseMetaData
& ResultSetMetaData
to get the details of a relation's attributes, before inserting the data into the TableModel
.
