Java练习（十八）---随机生成1-100中的10个数&倒序排列&求平均值&输出最大值最小值&判断是否有8

        int[] arr = new int[10];
        boolean shuchu = false;
        //随机生成1-100之间的10个数保存到数组
        for (int i = 0; i < 10; i++) {
            int a = (int) (Math.random() * 100);
            arr[i] = a;
            System.out.print(arr[i]+" ");
            if (arr[i] == 8){
                shuchu = true;
            }
        }
        if (shuchu) {
            System.out.println();
            System.out.print("数组中含有8");
        }
        //将数组进行正向排序
        for (int i = 0; i < arr.length - 1; i++) {
            for (int j = 0; j < arr.length - 1; j++) {
                if (arr[j + 1] < arr[j]) {
                    int temp = arr[j];
                    arr[j] = arr[j + 1];
                    arr[j + 1] = temp;
                }
            }
        }
        System.out.println();
        System.out.print(Arrays.toString(arr));//正常打印
        System.out.println();
        System.out.println("数组最大值="+arr[arr.length-1]);

        //将数组倒序排列
        int[] arr1 = new int[arr.length];
        for (int i = 0; i < arr1.length; i++) {
            arr1[i] = arr[arr.length - i - 1];
        }
        System.out.print(Arrays.toString(arr1));
        System.out.println();
        System.out.println("数组最小值="+arr1[arr.length-1]);

        //求出数组平均值
        int sum = 0;
        for (int i = 0; i < arr1.length; i++) {
            sum+=arr1[i];
        }
        System.out.println("数组平均值="+sum/ arr1.length);
