简单题

java输出可以使用System.out.format();

这个的使用方法与printf();相同。

import java.io.*;
import java.util.*;
import java.math.*;

public class Main {

    public static void main(String[] args)
    {
        Scanner cin = new Scanner(new BufferedInputStream(System.in));
        int a;
        while (cin.hasNext())
        {
            a = cin.nextInt();
            if (a == 0)
                break;
            BigInteger x = new BigInteger("1");
            for (int i = 2; i <= a; i++)
                x = x.multiply(BigInteger.valueOf(i));
            String st = x.toString();
            int[] ans = new int[10];
            for (int i = 0; i < 10; i++)
                ans[i] = 0;
            int len = st.length();
            for (int i = 0; i < len; i++)
                ans[(int)(st.charAt(i) - '0')]++;
            System.out.println(a + "! --");
            System.out.format("   (%d)%5d", 0, ans[0]);
            for (int i = 1; i < 5; i++)
                System.out.format("    (%d)%5d", i, ans[i]);
            System.out.println("");
            System.out.format("   (%d)%5d", 5, ans[5]);
            for (int i = 6; i < 10; i++)
                System.out.format("    (%d)%5d", i, ans[i]);
            System.out.println("");
        }
    }
}
