现在输入n个数字，以逗号，分开； 然后可选择升或者降序排序；

import java.util.Random;
import java.util.StringTokenizer;
import java.util.Arrays;

public class Test {
	public static void main(String[] args) {

		String[] ss = new String[10];
		Random random = new Random();
		StringBuffer sb = new StringBuffer();
		for (int i = 0; i < ss.length; i++) {
			sb.append(random.nextInt(100)).append(",");
		}
		StringTokenizer tok = new StringTokenizer(sb.toString(), ",");
		// 返回有多少个被分割元素
		int[] result = new int[tok.countTokens()];
		// 把分割得到的数字存到数组中去。
		for (int i = 0; i < result.length; i++) {
			result[i] = Integer.parseInt(tok.nextElement().toString());
		}
		// 排序
		Arrays.sort(result);
		for (int i = 0; i < result.length; i++) {
			if (i == 0) {
				System.out.print(result[i]);
				continue;// 第一个元素的前面不打印“，”
			}
			System.out.print("," + result[i]);
		}
		System.out.println();// 输出：2,11,24,354,654,666,3234,3544,5435,6554
