Primitive Types
What distinguishes compile-time polymorphism from run-time polymorphism in relation to method invocation in Java?
Method overloading facilitates compile-time while method overriding enables run-time polymorphism.
Compile-Time uses class inheritance hierarchies whereas Run-Time relies solely on interface implementation.
Static type checking allows for compile-time while continuous reassignment grants run-time capabilities.
The number of parameters in methods determines compile-time versus variable types being considered at run-time.
When implementing an interface 'Operable' in a vehicle management system, which class should directly realize all abstract methods of 'Operable' given that Car and Bicycle classes extend Vehicle?
Operable itself cannot be instantiated.
Vehicle
Car
Bicycle
Which term describes an error in a program that causes it to execute unintended actions?
Feature
Patch
Upgrade
Bug
In terms of reducing potential errors related to data manipulation in an algorithm in Java, which feature should be prioritized?
Dynamic method dispatch
Strong type checking
Just-in-time compilation (JIT)
Garbage collection
Why is Java considered architecture-neutral?
Java can easily connect to the internet and to file systems
Once Java is compiled, it can be run on any device
Java is a compiled language, unlike Python
Java is used by most architects
What does the System.out.print() method do?
Prints output to the console and puts the cursor on a new line
Prints output to the terminal
Prints output to the console without moving the cursor
Prints output to a file provided by the user
What is the boolean result of the expression (5 > 4)?
null
error
false
true

How might you optimize tail-end recursion in Java implementation calculating very large factorial numbers precisely taking into consideration stack overflow risks usually associated traditional approaches?
Through iterative loop transformation store intermediate results in a BigDecimal object instead of relying solely on system stack memory calls.
Delegating heavy lifting computations to a separate thread and employing concurrency techniques to alleviate the main application workload.
By increasing Xms parameter in JVM startup settings to allocate additional frame space beforehand to prevent overflow.
Utilizing memoization cache for factorials already computed to reuse in future calculations, despite not directly impacting recursion itself.
What is the primary purpose of debugging in programming?
To improve the speed of a program's execution.
To interact with users and gather feedback on a program.
To add new features to an existing program.
To find and fix errors or bugs in code.
When comparing recursive and iterative implementations of the same function in Java, under what circumstance might iteration be more efficient than recursion?
When solving problems that exhibit optimal substructure
When minimizing memory usage is crucial
When dealing with small input sizes
When implementing divide-and-conquer strategies
