Regular expressions in Java

 Regular expressions in Java

Regular expressions are a way to match patterns in strings. They allow you to search for specific characters, words, or patterns, and can be used for tasks such as data validation and text processing.

Example code:

java

String input = "The quick brown fox jumps over the lazy dog.";

Pattern pattern = Pattern.compile("\\b\\w{5}\\b");

Matcher matcher = pattern.matcher(input);

while (matcher.find()) {

    System.out.println("Match: " + matcher.group());

}
