Java编程过程中,Integer对象(或其它继承自Number类的包装类对象)使用Number包装类内置的compareTo()方法来比较调用对象和参数之间的大小的时候,Java的集成开发环境IDE或编译器给出了提示:The method compareTo(Integer) in the type Integer is not applicable for the arguments (Float),后类似的提示,这是怎么回事呢?

Comparator接口位于java.util包下,而Comparable接口位于kava.lang包下。 对于Comparator接口,可以看到它的compare()方法的参数时两个对象,比如我们对Cat类进行比较,那么这里就是两个要比较的Cat类的对象,所以可以有一个单独的类实现Comparator。 对于Comparable接口,它的方法只有一个对象作为参数,所以要比较的类需要实现Com...
