As a java developer I often wanted to execute a small piece of code and test it quickly without opening an IDE. Some times the same bit of code we want to execute often and use the result somewhere. May be even we want to share that bit of joy with others. One of the solutions is JDoodle.com.

JDoodle.com helps compile and execute java programs online. It has simple interface. Share your thoughts about JDoodle.com here in comment.

Try some default shares

Hello World
Hello World with Method
Example with import and Input Arguments

some of the features you may like is

1. auto complete import - just type the class name it will come with whole bunch of suggestions for you, just select the one you want and click Tick button.

2. Recents - you can see all the recently executed codes in the browser here. even you can ask JDoodle.com to remember this between same browsers different session.

3. Share - makes sharing easier. Not all your code shared by default, so you can always control what to share and what not to.

1) Check only @Id field
Drawback: Before persisting, @Id field is null; in this case, there are no way to check equality



Once you get the ID (after persisting in your case) only your object becomes complete, if id is the unique identifier for your entity, this is the best candidate.

What you are going to compare with incomplete object? even I dont think you will place it in HashMap without id.
here null means, reference not pointing to any object in the heap. so for any type of object reference we can say that it is not pointing to any object. hope helps.

You need to log through code like log.info, log.error, etc in your code....
My view is as long the number is not associated with some thing it does not have any meaning, 15 can represent a day in a month or money or age, etc etc. it can be a symbol as well. but words are self explanatory (when they are meaningful).
As per your requirement you need to do something when an application starts, so it will solve your problem, after that even if container destroys the servlet, I dont think there is a problem.
Main Method is the communication medium between jvm and user, so it should receive the input from user in user understandable format ie String...
write a standalone program which will check the status of the external system in certain time interval and notify you
