Why main method is public static in Java

The main method in Java is typically declared as public and static for several reasons:

• Accessibility: Declaring the main method as public allows it to be accessed and executed from outside the class in which it is defined. This is necessary because the Java Virtual Machine (JVM) needs to invoke the main method to start the execution of a Java program.
• Entry Point: The main method serves as the entry point for the Java program. When the program is run, the JVM looks for the main method with the specific signature (public static void main(String[] args)) and starts executing the code inside it.
• Static Context: The main method is declared as static so that it can be invoked without having to instantiate an object of the class. Static methods belong to the class itself, not to specific instances of the class. This allows the JVM to call the main method directly using the class name, without creating an instance of the class.
• Consistency: Making the main method public and static is a convention established by the Java language. It ensures consistency across different Java programs, as the JVM expects the main method to have this specific signature.

It's worth noting that while the main method is typically declared as public static, it is possible to declare it with different access modifiers (e.g., private, protected) or without the static keyword. However, doing so would prevent the JVM from finding and executing the main method correctly, resulting in the program not being able to run as expected.
