Debug tool
When
java has some error, we could use "e.printstack()" to see the error message, and we could how the application goes step by step , one class by class, function by function. That is very helpful.
But the problem, these info will be there just when java has error exception. My question, when we run a non-exception application, how could I see those message, step by step , one class by class, function by function ?
Any suggestion ?
Thanks
