Matcher Class in Java

The Matcher class is part of Java’s regular expression package (java.util.regex). It works with a compiled regular expression (a Pattern object) to perform match operations on a character sequence (such as a string). The Matcher class provides methods to check if the pattern matches the input, to search for occurrences, and to extract or manipulate matched subsequences. This lesson will introduce the key methods of the Matcher class and demonstrate how to use them with simple examples.
