Difference between invokevirtual & invokespecial?

Question

Java

Hello! Am I understanding the difference between the two instructions correctly?
invokevirtual is used to call methods on an object, and a reference to the object that owns the class (aload i) is pushed onto the stack as a parameter. invokespecial is used to initialize a class and call private methods. In the case of calling private methods, a reference to the owner object (this) is always written to the stack with the aload 0 command.
Please respond to those who know. Thank you very much
