scala> print "Hello"
<console>:1: error: ';' expected but string literal found.
       print "Hello"

scala>

这应该打印"你好"

如果你问得好,它确实有效:

scala> object please {
     |   val print = Predef.print _
     | }
defined module please

scala> please print "Hello"
Hello

Answer 2

使用正确的语法:

scala> print("Hello")
Hello
