Logical Equality and Compare References
来源：互联网 发布：mac软件安装文件夹 编辑：程序博客网 时间：2024/05/10 15:24
In Java, == compares object references only. It doesn’t perform a logical equality check. You use the equals method for that purpose.
In contrast, Scala uses == for logical equality, but it calls the equals method. A new method, eq, is available when you want to compare references, but not test for logical equality.
