在java中旋转数组的一部分

public class RotateArray {
    public static void rotate(int[] arr, int start, int end) {
        int length = end - start + 1;
        int[] temp = new int[length];
        
        // 复制需要旋转的部分到临时数组
        System.arraycopy(arr, start, temp, 0, length);
        
        // 反转临时数组
        for (int i = 0; i < length / 2; i++) {
            int tempValue = temp[i];
            temp[i] = temp[length - i - 1];
            temp[length - i - 1] = tempValue;
        }
        
        // 将反转后的临时数组复制回原始数组
        System.arraycopy(temp, 0, arr, start, length);
    }
    
    public static void main(String[] args) {
        int[] arr = {1, 2, 3, 4, 5, 6, 7};
        int start = 2;
        int end = 5;
        
        rotate(arr, start, end);
        
        for (int num : arr) {
            System.out.print(num + " ");
        }
    }
}
