LinkedBlockingQueue toString() method in Java Last Updated : 18 Sep, 2018 Summarize Comments Improve Suggest changes Share Like Article Like Report The toString() method of LinkedBlockingQueue returns a string representation of this collection. The string representation consists of a list of the collection's elements in the order they are returned by its iterator, enclosed in square brackets ("[]"). The adjacent elements are separated by the characters ", " (comma and space). The elements are converted to strings as by String.valueOf(Object). Syntax: public String toString() Parameters: This method does not accept any parameters. Returns: This method returns a string representation of this collection.
