Java数组 反转

数组的反转

方式一：

        String[] reverse = new String[]{"AA", "BB", "CC", "DD", "EE", "FF", "GG"};

        for (int i = 0; i <= (reverse.length - 1) / 2; i++) {
            String tmp = reverse[i];
            reverse[i] = reverse[reverse.length - i - 1];
            reverse[reverse.length - i - 1] = tmp;
        }

方式二：

        String[] reverse = new String[]{"AA", "BB", "CC", "DD", "EE", "FF", "GG"};

        for (int i = 0, j = reverse.length - 1; i < j; i++, j--) {
            String tmp = reverse[i];
            reverse[i] = reverse[j];
            reverse[j] = tmp;
        }
