What is Regular Expressions Overview and Usage about?

Regular expressions are patterns used to match strings. They define a search pattern that may match one or more times or not at all in a given string. Common symbols used in regular expressions include period, caret, brackets, and pipe symbols to match or find specific characters. Quantifiers like asterisk, plus, and curly brackets are used to define how many times an element can occur. Java has built-in support for regular expressions through string methods like matches(), split(), and replace().
