Core Java Programming Course- "OR" Operator

The video tutorial explains the use of the pipe operator to select one option from a group in string patterns. It covers how to specify multiple options using the pipe symbol and provides examples of valid and invalid matches. The tutorial also demonstrates testing patterns to verify if a string matches the specified criteria.

What is the primary function of the pipe operator in a pattern?

• To combine multiple strings

• To reverse the order of characters
