oop - How do I create a Perl class? -


I am writing the Perl sections to remove the redundancy from the scripts and since when I made a lot of class in Perl Trouble is the classes properly, so does anyone have the best practice example of class?

I have the biggest question that there should be no global variable in the module, so how do you use sub-variables in the module? Like Java-> Foo = 10;

Actually just give me a class written in Java or C # or even C ++ and write the same in Perl. Additional points to show how to fix private, protected and public square variables Inheritance and Interface I think that would be helpful.

There is a specific way of creating a Pearl object, there is a BlessingHashref object insertion that has its set of hash keys Can store data against 

  Package SampleObject; Strict use; Use warnings; Sub New {my ($ class,% args) = @_; Return {% args}, $ square blessing; } Sub sample_method {my ($ self) = @_; Print $ self-> {Sample_data}; }

and use: 

  My $ obj = SampleObject-> New (sample_data = & gt; 'hello world', more_data => 'blah blah blah'); $ Obj- & gt; Sample_method (); Alternatively, accessor / mutator methods can be added (class :: accessor, class :: accessor :: series, etc.) to be easily installed - they are valid Making data and encryption easier is easy to do (it has not been implemented in Perl, you have to make sure that your code does not go to any suitable accessor / mutator and directly accesses data in the file).
