main方法是Java Application程序执行的入口点,关于main方法头以下( )是合法的。A.pubUc statk void main()B.public static void main (String[]args)C.public static int main (String[]arg)D.public void main (String arg[])
在 Java 中,main 方法书写正确的是()A.public void main(String[] args)B.public static main(String[] args)C.public void static main(String[] args)D.public static void main(String[] arg)
