This 1Z0-811 practice question tests your understanding of java basics and syntax. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Exhibit
public class InitOrder {
static { System.out.print("A "); }
{ System.out.print("B "); }
public InitOrder() { System.out.print("C "); }
public static void main(String[] args) {
new InitOrder();
}
}
Refer to the exhibit. What is the output when running the main method?
Exhibit
public class InitOrder {
static { System.out.print("A "); }

public InitOrder() { System.out.print("C "); }

}
}
A
B A C
Why wrong: Static block runs before instance creation.
B
A B C
Static init block, then instance init block, then constructor.
C
A C B
Why wrong: Instance init block runs before constructor body.
D
C B A
Why wrong: Static block runs first, then instance init, then constructor.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A B C
The correct answer is B because, in Java, when an object of a subclass is created, constructors are executed from the topmost superclass down to the subclass. Assuming the exhibit shows class C extends B extends A, with each constructor printing its class name, the output will be A B C.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Oracle often tests the order of constructor execution in inheritance, and the trap here is that candidates mistakenly think constructors execute from child to parent (like destructors in C++) or confuse the output order with method overriding behavior, leading them to choose 'C B A' or 'B A C'.
Detailed technical explanation
How to think about this question
In Java, when a class is instantiated, the constructor chain ensures that the superclass constructor is executed before the subclass constructor, either through an explicit `super()` call or an implicit one inserted by the compiler. This guarantees that inherited fields are initialized before any subclass-specific code runs. A subtle behavior is that if a superclass constructor calls an overridable method, the subclass's override will be invoked before the subclass constructor body executes, which can lead to unexpected results if the subclass fields are not yet initialized.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 1Z0-811 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
