Q2Domain Verified
Considering the "The Complete Java OOP & SOLID Principles Course 2026," a Java developer implementing the Liskov Substitution Principle (LSP) would ensure that if `S` is a subtype of `T`, then objects of type `T` may be replaced with objects of type `S` without altering any of the desirable properties of the program. Which of the following Java constructs, if misused, most commonly leads to violations of LSP?
Static final variables
Abstract classes with concrete methods
Private constructors
Method overriding that throws unchecked exceptions not declared by the superclass
Q3Domain Verified
Within the framework of "The Complete Java OOP & SOLID Principles Course 2026," when a Java application encounters a situation where a `Dog` object is expected, but a `Cat` object is passed, and the program behaves unexpectedly (e.g., barking instead of meowing), this is a classic illustration of a violation of which SOLID principle?
Dependency Inversion Principle
