将Java对象转换为整数

Question

以下代码显示的错误是:无法将对象转换为整数.我不知道还有什么可以包括它.

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);
            }
        };
    }

Answer 1

你想要的是:

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