To gather the additional information provided in comments:

• @Hugo注意到＃表示法依次来自HTML锚点


• @maksimov指出那个 Object.method 是调用静态方法的Java语法，这可能会产生误导

• @Hugo notes that the # notation in turn comes from HTML anchors
• @maksimov points out that Object.method is the Java syntax to call static methods, which could be misleading

UPDATE

Java 8为方法引用带来了一种新语法，现在它似乎变得更受欢迎 - 所以 Object＃toString 现在倾向于写成 Object :: toString 。

Java 8 brings a new syntax for method references, which now seems to become more popular - so Object#toString tends to now be written Object::toString.
