Scala中==和.equals有什么区别? [英] What's the difference between == and .equals in Scala?

问题描述

Scala中的==和.equals()有什么区别，什么时候使用?

实现与Java中的实现相同吗?

相关问题讨论AnyVal的具体情况.更一般的情况是Any.

解决方案

您通常使用==，它会路由到equals，但会正确处理null.参考等式(很少使用)为eq.

What is the difference between == and .equals() in Scala, and when to use which?

Is the implementation same as in Java?

EDIT: The related question talks about specific cases of AnyVal. The more general case is Any.

解决方案

You normally use ==, it routes to equals, except that it treats nulls properly. Reference equality (rarely used) is eq.
