如何获取JTable中所有行的值并使用定界符和换行符将它们拆分？

Question

Say I had a table like this:

|ID|Name|Work|Age|
|31|John|IT  |31 |
|32|Jane|IT  |22 |

And I wanted to convert the values in the cell to string with delimiters(,) and newline like this:

31,John,IT ,31 
32,Jane,IT ,22 

What code would I need to punch in in order for this to happen?

The following method convert a JTable in CSV String

public static String exportToCSV(JTable tableToExport) {
    StringBuilder stringBuilder = new StringBuilder();
    TableModel model = tableToExport.getModel();

    for (int i = 0; i < model.getRowCount(); i++) {
        for (int j = 0; j < model.getColumnCount(); j++) {
            stringBuilder.append(model.getValueAt(i, j).toString()).append(",");
        }
        stringBuilder.append("\n");
    }

    return stringBuilder.toString();
}
