Converts the specified object to String according to the following rules:
obj is already a String object (i.e. an instance of
java.lang.String), the function works simply as the type cast operator,
same as in Java: (String) obj
obj is an array
(i.e. an instance of java.lang.Object[]),
the function returns a concatenation of the string representations
of all array elements separated with spaces.
The null elements will be ignored and excluded
from the representation.
obj is null, an empty string is returned
obj.toString()
You may call this function in a more method-like style:
obj.toString()
