Question 1
In Java 17, a software engineer at Banco do Brasil is designing a payment processing module where a base class 'PaymentProcessor' defines a method 'public void process(Transaction tx)'. A subclass 'PixProcessor' overrides this method. At runtime, when an instance of 'PixProcessor' is referenced via a variable of type 'PaymentProcessor' and 'process(tx)' is invoked, which mechanism determines that the 'PixProcessor' implementation must execute?
Correct Answer:
Dynamic method dispatch (late binding) resolved at runtime via the virtual method table (vtable)
Question 2
A banking system requires constructing complex 'LoanProposal' objects with varying attributes such as applicant rating, collateral items, guarantor data, and repayment schedules. Which GoF design pattern separates the construction of this complex object from its representation, allowing the same construction process to create various representations?
Correct Answer:
Builder Pattern
Question 3
A developer at Banco do Brasil refactors a monolithic 'AccountService' class that previously calculated interest, persisted database records, formatted PDF statements, and sent SMS alerts. By decomposing this class into 'InterestCalculator', 'AccountRepository', 'StatementGenerator', and 'NotificationService', which SOLID principle is most directly applied?
Correct Answer:
Single Responsibility Principle (SRP)
Question 4
When working on a feature branch 'feat/pix-keys' in Git, a developer wants to incorporate the latest commits from 'main' while keeping a completely linear commit history without creating an extra merge commit. Which Git command should be executed?
Correct Answer:
git rebase main
Question 5
Consider the following Java Streams pipeline intended to calculate the total transaction volume for approved credit operations: ```java BigDecimal total = transactions.stream() .filter(t -> t.getStatus() == Status.APPROVED) .map(Transaction::getAmount) .reduce(BigDecimal.ZERO, BigDecimal::add); ``` What is the nature of the operations 'filter' and 'reduce' in this pipeline?
Correct Answer:
'filter' is an intermediate lazy operation, while 'reduce' is a terminal eager operation.
