Question 462 of 509
Quick Answer
The correct answer is that super() must be the first statement in a subclass constructor. This requirement exists because Java enforces a strict initialization order: the superclass constructor must complete before any subclass fields or logic are accessed, ensuring the inherited state is fully set up before the subclass adds its own. On the Oracle Java Foundations 1Z0-811 exam, this rule is frequently tested as a fundamental principle of inheritance, often appearing in multiple-choice questions where a trap option places super() after other statements or omits it entirely. The key technical concept is that the compiler automatically inserts a no-argument super() call if none is written, but if the superclass lacks a no-arg constructor, you must explicitly call a parameterized super() as the very first line. A reliable memory tip is "super first, then subclass thirst"—the superclass constructor always drinks first before the subclass gets its turn.

Correct answer & explanation
✓
super(); as first statement
In Java, a call to the superclass constructor using `super()` must be the first statement in a subclass constructor. This ensures that the superclass initialization completes before any subclass-specific code executes, maintaining the inheritance chain. Option B correctly identifies this requirement.
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 misconception that `super()` can be placed anywhere in the constructor body, leading candidates to choose option A, when in fact Java strictly requires it as the first statement.
Detailed technical explanation
How to think about this question
Under the hood, the Java compiler enforces that the first statement in any constructor (except `Object`'s) is either `super()` or `this()` (for same-class constructor chaining). If omitted, the compiler inserts an implicit `super()` call to the no-arg superclass constructor. This rule prevents the subclass from accessing uninitialized superclass fields, a common source of bugs in real-world frameworks like Spring or Hibernate where constructor injection relies on proper initialization order.
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.
