Question

下面的代码我已经将数组的中点设置为5但现在我想将中点移动到最后，当它移动到结尾时，其他数字将向左移动以填补空白。没有arraylists大声。

        int mid = length/2;

    for (int i = array.length-1 ; i> mid; i--) { 
        array[i] = array[i-1]; 
    } 
    array[mid] = 5;

Answer 1

这样的东西？

int mid = array.length/2;

for (int i = mid; i < array.length-1; i++)
{
    int temp = array[i];
    array[i] = array[i+1];
    array[i+1] = temp;
}

Answer 2

public static void main(String[] args) {
    int array[] = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
    int mid = array.length / 2;
    array[mid] = 5;

    // my code starts here...

    int aux = mid; // aux isn't necessary if you can lost mid value
    int backup = array[mid]; // save the middle value

    for (; aux < array.length - 1; aux++) { //starting at middle until the end of array
        // current pos receives the next value;
        array[aux] = array[aux + 1];
    }

    array[array.length - 1] = backup; // restore the middle value at the end;
}

该代码在[1,2,3,4,6,7,8,9,5]中转换[1,2,3,4,5,6,7,8,9]。这是你想要的吗？
