Zviki Cohen publishes 5 ways to track Java execution based on his own experience of exploring and understanding the code that others have written. He found that simple reading of source code (in some cases, decompile code) could be a tedious and erroneous process. Instead, he recommends 5 different run-time tracking methods to observe when Java code is running, eliminating many of the disadvantages of learning other people's code. The following conden
