My understanding is that private means being private to an instance. Private methods can't be called with an explicit receiver, even self. To call a private method, I have to go through a process like below:
class Sample def foo baz end private def baz end end Sample.new.foo This will call the private baz method. Is there a way to directly call a private method with an explicit receiver?

Accessing Private Constructors of a class To access the private constructor, we use the method getDeclaredConstructor(). The getDeclaredConstructor() is used to access a parameterless as well as a parametrized constructor of a class.
How to access the Private Member Function in C++? A function declared inside the private access specifier of the class, is known as a private member function. A private member function can be accessed through the only public member function of the same class. rNo is used to store the roll number of the student.
We can call the private method of a class from another class in Java (which are defined using the private access modifier in Java). We can do this by changing the runtime behavior of the class by using some predefined methods of Java. For accessing private method of different class we will use Reflection API.
Yes, this is possible with Kernel#send:
receiver.send :method_name, parameters Though there are workarounds like BasicObject#instance_eval, or Kernel#binding manipulations, the common way to call private method is to call send on the receiver.

Using BasicObject#instance_eval, you can call private method.
class Sample private def baz 'baz called' end end Sample.new.instance_eval('baz') # => 'baz called' Sample.new.instance_eval { baz } # => 'baz called' If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
