Call Java logging method?

Question

Are there any tools that can be used to register all method calls from running a java application?

eg.

String str = "...";
String anotherString = str.trim();

should write something like this:

..method call trim() from class java.lang.String

You need a profiler.

Some popular profilers are: JProfiler , which has different ways to record a method call, both at the CPU level and at the memory level.

VisualVM is another

Many IDEs (I know Netbeans and Eclipse) have their own profilers that you can use.

You can use the @Loggableannotation from jcabi-aspects , which wraps all the methods you want to debug, using a simple logging mechanism:

@Loggable(Loggable.DEBUG)
public String load(URL url) {
  return url.openConnection().getContent();
}

It is registered through SLF4J .
