这样子吗？
```java
public static void main(String[] args) {
int[] arr = {2, 1, 5, 7, 4, 9, 8, 5, 6};
int l = 0;
int r = 0;
while (r < arr.length) {
if (arr[r] % 2 == 0) {
r++;
} else {
int odd = arr[r];
for (int i = r; i > l; i--) {
arr[i] = arr[i - 1];
}
arr[l] = odd;
l++;
r++;

}
}
System.out.println(Arrays.toString(arr));
}
```
