Cast a Java Object to Integer

Error shown from the below code is: Cannot Cast an object to integer. I don't know what else will i include to cast it.

private RowFilter filter(final int itemsPerPage,final int target) {
        return new RowFilter() {
            public boolean include(Entry entry) {

                /* HERE I AM RECEIVING ERROR: Multiple markers at this line
                - Type mismatch: cannot convert from  Object to int
                - Cannot cast from Object to int */
                int ei = (int) entry.getIdentifier();

                return (target * itemsPerPage <= ei && ei < target
                        * itemsPerPage + itemsPerPage);
            }
        };
    }
Solution

  • What you want is:

    int ei = ((Integer) entry.getIdentifier()).intValue();
