Which statement is true about the main() method?
Which statement is true about the main() method?
The main() method is invoked by the Java Runtime Environment (JRE). This is because the main() method serves as the entry point for Java applications, and when a Java program is executed, the JRE looks for the main() method to start the program. This method is not required to be defined within a public class, nor does it return any value indicating successful execution. It is also not inherently a final method.
The answer is letter A, you don't need to think too much. As I have noticed, many simple questions in the OCA exam the answers are usually the most obvious precisely for you to be suspicious and spend more time on them, because it is a very careful exam and any extra time is needed.
D is not correct (you can also declare main() in package-private classes.)
a is currect
Option D is right answer
The main() method in Java is the entry point of a Java program, and it must be defined within a public class. This is a fundamental requirement of the Java language. Without a public class containing the main() method, the Java Virtual Machine (JVM) will not be able to find and execute the program.
D is correct the main() method must be defined within a public class in Java. When a Java program is executed, the Java Virtual Machine (JVM) looks for a public class with a main() method to begin the program's execution. If the main() method is not located within a public class, the JVM will not be able to find it and the program will not run.
