我想知道一维数组中，怎样求其中的最大值，最小值以及差值···请教指点一些代码

我简单写了一个：
public class Suibianxiexie {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        int[] score = { 4, 6, 5, 7, 8, 9, 4, 3, 9, 1 };
        int min = score[0];
        int max = score[0];
        int m = 0, n = 0;
        for (int i = 0; i <= score.length - 1; i++) {
            if (score[i] > max) {
                max = score[i];
                m = i;
            } else if (min > score[i]) {
                min = score[i];
                n = i;
            }
        }
        System.out.print("最大数为:" + max + "下标为:" + m + "\n最小数为:" + min + "下标为:"
                + n);
    }
}

忘了写差值了，呵呵呵：
public class Suibianxiexie {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        int[] score = { 4, 6, 5, 7, 8, 9, 4, 3, 9, 1 };
        int min = score[0];
        int max = score[0];
        int m = 0, n = 0;
        for (int i = 0; i <= score.length - 1; i++) {
            if (score[i] > max) {
                max = score[i];
                m = i;
            } else if (min > score[i]) {
                min = score[i];
                n = i;
            }
        }
        System.out.print("最大数为:" + max + "下标为:" + m + "\n最小数为:" + min + "下标为:"
                + n+"\n最大值与最小值的差值为:"+(max-min));
    }
}

谢谢你，不过我要得是如何求得最大值，最小值，还有两者的差值，嘿嘿

好好的程序，嘿嘿  受教了  我们老师现在教 框架，我先学点数组写法，嘿嘿   数组好些不那么繁琐
