Core Java Programming Course- Quantifiers in RegEx (regular expressions)

The video tutorial explains the use of quantifiers in regular expressions, focusing on asterisk (*), plus (+), question mark (?), and curly brackets {}. Each quantifier is discussed in terms of its function in matching preceding characters or blocks of characters. The tutorial provides examples and explains how to use these quantifiers to specify the number of repetitions in a pattern, making it easier to match strings in Java and other programming languages.
