从数字字符串中找到最大值和最小值

 

   /**
     * find the max and min from String
     */
    public static String highAndLow(String numbers) {
        String retStr = "";
        String[] strAry = numbers.split(" ");
        int[] intAry = new int[strAry.length];
        for (int i = 0; i < strAry.length; i++) {
            intAry[i] = Integer.parseInt(strAry[i]);
        }
        Arrays.sort(intAry);
        retStr = String.valueOf(intAry[intAry.length - 1]) + " " + String.valueOf(intAry[0]);
        System.out.println(retStr);
        return retStr;
    }

　　

    public static void main(String[] args) {
        highAndLow("8 3 -5 42 -1 0 0 -9 4 7 4 -4");
    }

　　结果：42 -9
