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.
Which TWO statements are true about the main method?
It must be declared final.
Why wrong: Final is not required.
It must be declared public.
Required for JVM to access.
It must return an int.
Why wrong: Main must return void.
It must be declared static.
Required to be called without an instance.
It cannot be overloaded.
Why wrong: Overloading is allowed.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
It must be declared public.
Option B is correct because the Java Language Specification (JLS) requires the main method to be declared public so that the JVM can access it from outside the class. Option D is correct because the main method must be static, allowing the JVM to invoke it without creating an instance of the class.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
It must be declared final.
Why it's wrong here
Final is not required.
It must be declared public.
Why this is correct
Required for JVM to access.

It cannot be overloaded.
Why it's wrong here
Overloading is allowed.
Common exam traps
Oracle often tests the misconception that the main method must be final or cannot be overloaded, but the JLS only mandates public, static, and void, and overloading is permitted as long as the standard signature is present.
Detailed technical explanation
The JVM looks for a specific signature: public static void main(String[] args). The method is invoked by the JVM's bootstrap class loader, which calls it via reflection; making it static avoids the need to instantiate the class. Overloading main is allowed but the JVM ignores overloaded versions that do not match the exact signature, which can be useful for internal testing or alternative entry logic.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
