我正在尝试使用 apache commons 集合和谓词，如下所示：
List<Cat> bigList = ....; // master list
Collection<Cat> smallList = CollectionUtils.select(bigList, new Predicate() {
public boolean evaluate(Object o) {
Cat c = (Cat)o;
return c.getFavoriteFood().equals("Wiskas")
&& c.getWhateverElse().equals(Something);
}
});
我的类路径中的罐子是：
commons-beanutils-1.8.3.jar
commons-collections-3.1.jar
commons-logging-1.1.jar
但在运行时我得到以下异常：
