从Java创建Scala对象：构造函数未定义

Question

I'm a novice in scala, so, sorry for a newby question :)

When I was trying to create a scala object in a Java class:

MyScalaObj mySo = new MyScalaObj();

I got error The constructor MyScalaObj() is undefined. Here is the code of MyScalaObj:

object MyScalaObj {
 def printSomething(something: String){
   println(something)
 }
 def main(args: Array[String]) {
    printSomething("Hello, world!")
 }
}

So, it seems that I should use only scala classes for such situation and I cannot create an object for java from a scala object, can I?

Thanks!

As Bob Dalgleish said, a scala object is a singleton, so, you cannot rich its constructor. Also, there is useful reading for the subject.

Thanks!
