This is my code. It seems the error is beca

Answer 1

string[] args in main method is used to follow the prototype defined by the technology. If you dont used it then JVM will considered it as a simple method. Also as this is prototype then remember technology used 0 byte of an array. for ex:

               class MainDemo{
                    public static void main(){
                    System.out.println("I am main method without arg");
                }
                public static void main(String[] args){
                        main();   //As method is static so no need to create an object
                    System.out.println("MainDemo");
                }
                }

O/p for above will give:

 I am main method without arg 
 MainDemo

Regarding your code, you cannot define/declare any method inside main method. Use it outside main method but within class.
