That's not an error. It's just the result of trying to print out a
String array. The
toString() method on an array doesn't do anything clever, it just inherits from
Object. And the version of
toString() in
Object prints out something that's based on the class name and the hash code. You can look at the documentation to check:
java.lang.Object#toString(). The "[L" part indicates an array.
To get the effect you probably want, you need to iterate over the array and print out individual values.
