scala之空格调用函数

java和scala调用函数的区别

object.method();

在scala中，这样调用,don’t need the semi-colon:

object.method()

甚至都不用括号(and then you can omit the parentheses):

object.method

如果方法只有一个参数,

object.method(param)

你可以把点换成空格，而且可以把括号去掉(you can change the Scala syntax to use a space instead of a dot, while also dropping the parentheses):

object method param

Scala methods that take a single parameter can be invoked without dots or parentheses.
