Question

question 3
all java applications must have a method
a public static void main(string args)
b public static main(string args)
c public static main(string args)
d public static main(string args)
e public void main(string args)

Explanation:

In Java, the entry - point method for an application is public static void main(String[] args). The public access modifier makes it accessible from outside the class. The static keyword allows it to be called without creating an instance of the class. The void return type indicates it doesn't return a value. The method name main is a convention, and it must be in lowercase. The parameter String[] args (or String args[]) is used to pass command - line arguments.

• Option B: The method name Main (capitalized) is incorrect. In Java, the main method is named main (lowercase).
• Option C: It is missing the void return type.
• Option D: Incorrect method name (Main instead of main) and also missing the void return type.
• Option E: It is missing the static keyword. Without the static keyword, it cannot be called as the entry - point without creating an instance, which is not the way Java applications start.

Answer:

A. public static void main(String[] args)
