剑指Offer（书）：调整数组顺序使奇数位于偶数前面

public void reOrderArray(int[] array) {
    for (int i = 0; i < array.length; i++) {
        int indexEven = 0;
        boolean flagEven = false;
        for (int j = 0; j < array.length; j++) {
            if ((array[j] & 1) == 1) {
                if (flagEven) {
                    int temp = array[j];
                    array[j] = array[indexEven];
                    array[indexEven] = temp;
                    flagEven = false;
                }
