java - 将比较器对象存储在数组中

我为我的对象定义了4个比较器，如下所示:

public static Comparator<mObject> comp0 = new Comparator<mObject>() {

        @Override
        public int compare(mObject l, mObject r) {
            ...compare
        }
    };

public static Comparator<mObject> comp1 = new Comparator<mObject>() {

        @Override
        public int compare(mObject l, mObject r) {
            ...compare
        }
    };

public static Comparator<mObject> comp2 = new Comparator<mObject>() {

        @Override
        public int compare(mObject l, mObject r) {
            ...compare
        }
    };

public static Comparator<mObject> comp4 = new Comparator<mObject>() {

        @Override
        public int compare(mObject l, mObject r) {
            ...compare
        }
    };

现在我想用4个比较器创建一个数组，像这样:

public final static Comparator<mObject>[] Object_comparators = { comp0,
        comp1,
        comp2,
        comp3};

但是Eclipse强调了{..}之间的所有内容，就像它是一个错误一样。为什么这样做，我该如何解决呢？

最佳答案

您不能使用参数化的泛型类型创建类的数组。

如果您不介意丢失类型安全性，则可以执行以下操作:

Comparator[] list = new Comparator[4];

但是我的首选策略是使用List:

List<Comparator<mObject>> list = Arrays.asList(comp0, comp1, comp2, comp3);
