Scala使用varargs构造函数扩展Java类

Question

I have a java class with a varargs constructor:

class Foo {
   this(Bar... bars) { 
      ...
   }

How would I extend this class in Scala?

//doesnt compile
class NooFoo(bars: Bar*) extends Foo(bars)

Answer 1

您可以尝试使用class NooFoo(bars: Bar*) extends Foo(bars:_*)因为bar是Seq [Bar]，而Foo（bars：Seq [Bar]）不是Java类Foo的构造函数，所以它不会不编译。
