This Java tip illustrates an example of logging a method call. Method calls are logged
by using functions entering() and existing() of the logger class.
package com.library;
class Books{
public boolean myMethod(int p1, Object p2) {
// Log object entry
Logger logger = Logger.getLogger("com.library.Books");
if (logger.isLoggable(Level.FINER)) {
logger.entering(this.getClass().getName(), "Method",
new Object[]{new Integer(p1), p2});
}
// Method body
// Log exiting
boolean result = true;
if (logger.isLoggable(Level.FINER)) {
logger.exiting(this.getClass().getName(), "Method", new Boolean(result));
//If the method does not return a value
logger.exiting(this.getClass().getName(), "Method");
}
return result;
}
}

Here is a sample of the output using a simple formatter and the following call:
new com.library.Books().Method(123, "hello");
Jan 10, 2002 7:59:48 PM com.library.Books Method
FINER: ENTRY 123 hello
Jan 10, 2002 7:59:49 PM com.library.Books Method
FINER: RETURN true
Jan 10, 2002 7:59:49 PM com.library.Books Method
FINER: RETURN
