import org.apache.log4j.Logger; public class MyClass { private static final Logger LOGGER = Logger.getLogger(MyClass.class); public void myMethod() { LOGGER.trace("Entering myMethod"); // do some work... LOGGER.trace("Exiting myMethod"); } }
import org.apache.log4j.Logger; public class MyClass { private static final Logger LOGGER = Logger.getLogger(MyClass.class); public void myMethod(String arg1, int arg2) { LOGGER.trace("Entering myMethod with arg1=" + arg1 + " and arg2=" + arg2); // do some work... LOGGER.trace("Exiting myMethod"); } }In this example, we include variables in the trace message to log their values during method execution. The java org.apache.log4j Logger trace feature is part of the Apache Log4j package library.
