Here is an example of how to use the Matcher class from the logback library in Java:

import ch.qos.logback.core.pattern.parser.Node;
import ch.qos.logback.core.pattern.parser.Parser;

public class Example {
    public static void main(String[] args) {
        String pattern = "%date %level [%thread] %logger{10} [%file:%line] %msg%n";
        Parser<Node> parser = new Parser<Node>();
        Node node = parser.parse(pattern);
        
        Matcher<Node> matcher = new Matcher<Node>();
        boolean result = matcher.match("%d %p [%t] %c{10} [%F:%L] %m%n", node);
        System.out.println("Does the pattern match? " + result);
    }
}

This example creates a pattern string, which is then parsed into a Node object using a Parser. Then it uses the Matcher class to compare the parsed pattern with a test pattern, and it prints the result of this comparison .

Please note that

• You should import the relevant classes for logback
• The above code is just an example and it does not include the full context of a logging application.
