Java relational operators

Question

在Java中，类应该实现（扩展）什么接口（类），以便允许类的两个实例通过诸如“<”或“> =”之类的关系运算符进行比较？

Answer 1

This is not possible in Java.

If you want objects of your class to be comparable, implement Comparable .

Answer 2

Java does not support operator overloading, so you're out of luck. Implementing java.lang.Comparable or providing a java.util.Comparator is what you're supposed to do.
