public class F0091
{
public void main( String[] args )
{
System.out.println( "Hello" + args[0] );
}
}
What will be the output of the program, if this code is executed with the command line:
> java F0091 world
Answer: Option
Explanation:
Option D is correct. A runtime error will occur owning to the main method of the code fragment not being declared static:
Exception in thread "main" java.lang.NoSuchMethodError: main
The Java Language Specification clearly states: "The main method must be declared public, static, and void. It must accept a single argument that is an array of strings."

While including static in public static void main it is still giving error that cannot find or load main class.

When we access anything from any method then first we create object of this method after that we access but if we declare method is static then we can access anything from this method without create object.
That why we use before main static keyword.
