[JAVA] How to use String [] args

import java.util.*;

public class Main {

int ii[];

public static void main(String[] args) throws Exception {

// In the case of primitive type variable, NULL is included in the initial value, you have to NEW and create an instance //lengthで数えてもNULLなのでエラーになる、argsは何も入ってないと[0]の配列を作るのでNULLではない //lengthすれば0を返し、argsを指定すればヌルではないのでクラス名とハッシュコードを返す main m=new main(); Main Mainm=new Main();

    System.out.println(Mainm.ii);
    System.out.println(m.i);
}

}

class main{ int i[]; }
