Batch programming: defaulting user input

This is a really simple script which sets a variable to a default value if the user doesn't provide input when asked.

set /P val=Please enter value: || set val=default

If the user enters a value, the %val% variable is set to the given value. Otherwise (if the user simply pressed Enter) 'default' is used instead.

Neat :).

JTable in JScrollPane showing default column names

Well, back to the basics of Java...

Just in case anybody (that's including me ;-)) gets this problem (again) here is the solution.

Basic scenario: building a JTable with a non default model class extending AbstractTableModel as follows. I have omitted necessary includes and actually removed method bodies for simplification purposes.

Spot the error...

public class SyncOperationTableModel extends AbstractTableModel
{
    // attributes

    public SyncOperationTableModel(ArrayList syncOperations)
    {
        super();
        // initialize attributes
    }

    public int getRowCount()
    {
        // return the row count based on attributes (for instance)
    }

    public int getColumnCount()
    {
        // return column count base on attributes (for instance)
    }

    public String getColumName(int column)
    {
        // return column name
    }

    public Object getValueAt(int row, int column)
    {
        // return the value, 
        // by default setValueAt is not necessary 
        // (AbstractTableModel returns false to isCellEditable method)
    }

}

Symptom? The column names (getColumName(int column)) never get returned and are replaced with default names: A, B, C... At first sight this is strange, since I purposefully add the table to a JScrollPane (which should handle the table header automatically).

Solution? In the above code the getColumnName(int column) does not get called simply because I have created a new method named getColumName (i.e. with a missing 'n' to the 'column' part of the name). Stu-pid!

New method:

    @Override
    public String getColumnName(int column)
    {
        // code
    }

Reaaaaally hopeless... no wonder this was impossible to find despite GIYF. Now getting on to cell rendering - it's been a while... other silly mistakes ahead I am sure.

More news soon.

Thoughts in the meantime?
