Record every method execution

Question

Is there any way that I can log / record / monitor / view every execution of a method inside of a Java program.

For example:

12:30:12 someMethod("argument")
12:30:12 anotherMethos(1, 2, 3)
12:30:13 finalMethod("invalidInputHere1234")

Answer 1

Easy answer: modify the method, and insert logging statements.

Somewhat more complex answer, which works even if you can't modify the method: look into aspect-based programming.

Answer 2

Without modifying the code you could use a debugger or profiler that is able to record any state change, like the Chronon time travelling debugger.
