将 Java 对象投入整数
原标题:Cast a Java Object to Integer

从下面的代码显示错误 : 无法将对象投入整数 。 我不知道我还会包括什么来投出它 。

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);
            }
        };
    }
最佳回答

你想要的是:

int ei = ((Integer) entry.getIdentifier()).intValue();
问题回答

case cast exception need refactor as: int ei = ((Integer.parseInt(String.valueOf(entry.getIdentifier())).intValue());

我认为你的方法是返回 Integer 对象, 如果您需要这样做:

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