Scala lift list.length() error: Int does not take parameters

Posted on by

When using myList.length() you will get an error message similar to this one

[INFO] Compiling 10 source files to /.../target/classes at 1317721118837
[ERROR] /.../src/main/scala/code/lib/MyLib.scala:216: error: Int does not take parameters
[INFO] 	  var listLength = myList.length()

What the error means is that length is not a function, but simply a property and you should use myList.length and not myList.length()
