Logback

How many log lines will this code output if we set the debug logger level for the logback package?

package logback;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class LogbackExample {
    private static final Logger LOG = LoggerFactory.getLogger(LogbackExample.class);

    static {
        LOG.debug("LogbackExample online");
    }

    public static void main(String[] args) {
        LOG.warn("Logger level online");
        LOG.trace("main method online");
        LOG.info("All systems nominal");
        LOG.trace("Args passed: {}", (Object) args);
        LOG.error("no args passed!");
    }
}
