Solution

Break Down the Problem

  1. Identify the nature of the code given.
  2. Understand the concepts related to abstract classes and methods in programming languages like Java.
  3. Determine the validity of the syntax and semantics of the code provided.

Relevant Concepts

  1. An abstract class is a class that cannot be instantiated and may contain abstract methods, which do not have a body.
  2. Abstract methods must be implemented in subclasses.
  3. The private access modifier means that the method cannot be accessed outside of its own class.

Analysis and Detail

  1. The Shape class is declared as abstract, which is correct.
  2. The method calcArea is also declared as abstract, but it has been marked as private. This creates a problem since private methods in an abstract class cannot be overridden by subclasses because they are not accessible.
  3. Therefore, this code will result in a compilation error due to the combination of an abstract method being private.

Verify and Summarize

Upon analyzing the properties of abstract classes and methods, it is evident that a private abstract method is not valid in any context, leading to the conclusion that the code will not execute successfully.

Final Answer

False - The code will not execute successfully due to the private abstract method.
