注意事项:
                注意输出要有空格




参考代码:

import java.util.Scanner;

public class Main {

        public static void format(float N){

                System.out.printf("%6.2f \n",N);

                for(int i=0;i<2;i++){

                        System.out.printf("%6.2f ",N);

                }

                System.out.println();

                for(int i=0;i<3;i++){

                        System.out.printf("%6.2f ",N);

                }

        }

        public static void main(String[] arg){

                Scanner sc = new Scanner(System.in);

                float N = sc.nextFloat();

                format(N);

        }

}
