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."

@Akash : Use of private with psvm() will lead to runtime exception : nosuchmainfound.

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