java数组-利用索引求最值

    private static void method7() {
        int[] arr = {45, 66, 77, 88, 10};
        // maxIndex最值所在的 索引
        int maxIndex = 0;
        int minIndex = 0;
        for (int i = 1; i < arr.length; i++) {
            maxIndex = arr[maxIndex] > arr[i] ? maxIndex : i;
            minIndex = arr[minIndex] < arr[i] ? minIndex : i;
        }
        System.out.println("maxIndex: " + maxIndex);
        System.out.println("max: " + arr[maxIndex]);

        System.out.println("minIndex: " + minIndex);
        System.out.println("min: " + arr[minIndex]);
    }
