Quick Answer
The correct answer is that the main method must be declared public, static, and void. This signature is mandatory because the Java Virtual Machine (JVM) requires a consistent entry point to begin program execution; the public access modifier allows the JVM to access the method from outside the class, static enables invocation without creating an instance, and void indicates that the method does not return any value to the operating system. On the Oracle Java Foundations 1Z0-811 exam, this concept tests your understanding of the program’s starting point and often appears as a multiple-select question where common traps include forgetting the static keyword or mistakenly thinking the method can return an int. A reliable memory tip is to remember the order as "P-S-V" for public, static, void, which you can recall as "Please Start Very carefully" when writing your main method.
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 THREE statements about the main method are correct? (Choose three.)
It must be declared void.
No return value.
It must be declared static.
Called without instance.
It must be declared public.
Required for JVM access.
It must return an int.
Why wrong: Must be void.
It can be overloaded.
Why wrong: Overloading is allowed but not a required statement.
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 void.
Option A is correct because the main method in Java must be declared void, as it does not return any value to the JVM. The JVM invokes the main method as the entry point of a program, and a return type of void ensures no value is returned to the operating system.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Why it's wrong here
Must be void.
It can be overloaded.
Why it's wrong here
Overloading is allowed but not a required statement.
Common exam traps
Oracle often tests the misconception that the main method cannot be overloaded, but the trap is that overloading is syntactically allowed, even though only the standard signature serves as the program entry point.
Detailed technical explanation
The main method signature is strictly defined by the Java Language Specification (JLS) as 'public static void main(String[] args)'. The JVM uses reflection to locate this exact method; if it is missing or has a different signature (e.g., returning int), a runtime error occurs. Overloading the main method is allowed but does not affect the entry point; it is often used for testing or alternative invocation within the same class.
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.

Variation 1. Which TWO statements are true about the main method?
mediumWhy B: 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.
