Multiple private methods

[java4deepak]

Hi,

just have a doubt which came from a discussion, is there any advantage/disadvantage in breaking a private method into multiple private methods in a class. Even though all the private mthod calls once in the class.

Thanks in advance

You get the sames advantage as you always get from breaking a method up into multiple methods. Whether the method is private or public doesn't really make a difference.

Have you tried anything like this through code? Is there any code snippet that you have stuck up with while trying this?

Just checking,

thanks all..

i read making unnecessary multiple public mathod create performance issue where as for private method it's not as private is like final which doesn't have any reference outside. So apart from this advantage i just wanted to know is there any other concern may have... This came up in a code review session where as the single method is broken into multiple private methods.

I could see it being a design issue because you might not want to give access to all of the methods to just any class, but I'm not sure that would impact performance at all. Where did you read this?

I'm not sure what you're saying here.

If you're in a code review, you pretty much should probably just listen to the reviewer. You might also look into profiling your program to see any actual performance changes (or the lack thereof).
