Using java.lang.Float.class causing Cannot format given Object as a Number

Question

hi,
I have table and its model is default table model.
model = new javax.swing.table.DefaultTableModel(data,col) {Class[] types = new Class [] {
                java.lang.Object.class, java.lang.Object.class, java.lang.Object.class, java.lang.Float.class,  java.lang.Integer.class
            }; public Class getColumnClass(int columnIndex) {
                return types [columnIndex];
            }};I want to force the user to enter float number to fourth column and integer number to fifth column. but I am gettin an error "Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: Cannot format given Object as a Number" like this. cause of this error is "java.lang.Float.class". and when I use Integer instead of Float the is no problem. Could you please help ?

It depends on model data.
