B Correct answer
Explanation

The Java runtime looks for a method with the exact signature public static void main(String[] args) to start program execution. The array notation can be written as String[] args or String args[], both are equivalent. The method must be public, static, return void, and accept a String array as its parameter.

AI explanation

To answer this question, you need to understand the correct syntax for the main method in Java.

The main method is the entry point for a Java program. It is the method that is executed when the program is started. The correct declaration for the main method is:

Option B) public static void main(String args[])

Explanation for each option:

Option A) public static int main(char args[]) - This option is incorrect because the return type of the main method should be void, not int.

Option B) public static void main(String args[]) - This option is correct because it has the correct syntax for the main method. The main method must be declared as public, static, void, and must accept a single parameter of type String array.

Option C) public static void MAIN(String args[]) - This option is incorrect because the main method must be declared as "main", not "MAIN". Java is case-sensitive, so the method name must match exactly.

Option D) public static void main(String args) - This option is incorrect because the main method should accept a parameter of type String array, not a single String.

Option E) public static void main(char args[]) - This option is incorrect because the main method should accept a parameter of type String array, not a char array.

Therefore, the correct answer is B) public static void main(String args[]).
